Water is a fundamental component of our planet, covering approximately 71% of its surface. Yet, have you ever wondered how water does not simply fall off the Earth? The answer lies in the complex interplay between gravity and the unique shape of our planet. In this article, we will delve into the science behind this phenomenon, exploring the fundamental principles of gravity and the Earth’s shape that prevent water, and everything else, from tumbling into space. By understanding the forces at play, we can gain a deeper appreciation for the delicate balance that allows life to thrive on our remarkable blue planet.
Gravity, the force that governs the motion of objects on Earth, plays a crucial role in anchoring everything to the planet’s surface. As Sir Isaac Newton described in his famous law of universal gravitation, every particle of matter attracts every other particle with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them. This means that everything, from a tiny grain of sand to a massive mountain, exerts a gravitational pull on everything else around it. Consequently, the Earth’s immense mass generates a powerful gravitational field that permeates its surroundings, keeping objects firmly in place. However, this force alone does not account for why water does not fall off the Earth; the shape of our planet also plays a vital role.
Understanding Gravity
A. Definition of gravity
Gravity is defined as the force that attracts objects towards each other. It is one of the fundamental forces of nature and is responsible for the motion and behavior of objects on Earth and in space. Gravity is what keeps objects, including humans, firmly rooted on the surface of the Earth.
B. Role of gravity in keeping objects on Earth
Without gravity, objects on Earth would not stay on its surface. Gravity pulls everything towards the center of the Earth, creating a downward force that counteracts any upward force. This is why objects, including water, do not simply float away into space. The gravitational force of the Earth holds them firmly in place.
IShape of the Earth
A. Historical understanding of Earth’s shape
Throughout history, various cultures and civilizations have had different beliefs about the shape of the Earth. Early civilizations, such as the ancient Greeks, believed that the Earth was flat. However, as scientific knowledge advanced, it became clear that the Earth is actually spherical in shape.
B. Evidence supporting the round shape of the Earth
There are several lines of evidence that support the idea that the Earth is round. One of the earliest pieces of evidence was the observation of the Earth’s shape during lunar eclipses. The curved shadow of the Earth on the moon is consistent with a spherical Earth. Additionally, the circumnavigation of the Earth by explorers like Ferdinand Magellan provided further evidence of its shape.
IGravity and Earth’s Shape
A. How gravity relates to Earth’s shape
Gravity plays a crucial role in shaping the Earth. Under the force of gravity, the Earth has naturally formed into a spherical shape. The gravitational force acts equally from all directions towards the center of the Earth, causing the planet to assume a round shape.
B. The force of gravity and its distribution across the Earth
The force of gravity is not constant across the surface of the Earth. It is stronger at the poles and weaker at the equator. This variation in gravity is due to the Earth’s rotation, as well as its slightly flattened shape at the poles. These differences in gravitational force result in slight variations in weight depending on location.
IShape of the Earth
The shape of the Earth has been a topic of fascination and debate for centuries. In this section, we will explore the historical understanding of Earth’s shape as well as the evidence supporting the round shape of our planet.
A. Historical understanding of Earth’s shape
Throughout history, humans have proposed various theories about the shape of the Earth. One of the earliest known beliefs was that the Earth was flat, supported by the idea that the horizon appears flat to the naked eye. However, ancient Greek philosophers such as Pythagoras and Aristotle observed different shapes of Earth’s shadow during lunar eclipses, suggesting a spherical shape.
It was not until the 3rd century BCE that the concept of a spherical Earth became widely accepted thanks to the work of Greek mathematician and astronomer, Eratosthenes. By measuring the angle of the Sun at different points on Earth’s surface, he calculated the circumference of the Earth with remarkable accuracy.
B. Evidence supporting the round shape of the Earth
There are several lines of evidence that support the round shape of the Earth. One of the most straightforward pieces of evidence is the observation of Earth’s curved shadow during a lunar eclipse. As the shadow moves across the surface of the Moon, it always appears as a curve, which can only be explained by a spherical Earth.
Furthermore, the phenomenon of ships disappearing over the horizon is also indicative of Earth’s curvature. As a ship sails away from an observer, it gradually disappears from view, starting with the hull and gradually the mast. This consistent pattern suggests that the Earth curves away from us.
Additionally, satellite images of Earth from space clearly show a round shape, further confirming what we have known for centuries.
Understanding the round shape of the Earth is crucial in comprehending its gravitational forces. Without this shape, gravity would not distribute evenly, which would have significant implications for the behavior of objects on Earth’s surface.
In the next section, we will delve into the relationship between gravity and Earth’s shape. We will explore how gravity relates to Earth’s shape, the force of gravity, and its distribution across the Earth.
IGravity and Earth’s Shape
A. How gravity relates to Earth’s shape
Gravity plays a crucial role in determining the shape of the Earth. The force of gravity pulls objects towards the center of mass, creating a spherical shape. The more mass an object has, the stronger its gravitational force. In the case of the Earth, the immense amount of mass pulls everything towards its core, resulting in a nearly spherical shape.
Gravity and the Equilibrium Shape:
The Earth’s shape also finds equilibrium through the gravitational force. The force of gravity acts in every direction towards the center, causing the Earth to settle into a shape that minimizes gravitational potential energy. This equilibrium shape is a sphere, as it evenly distributes the mass and minimizes the overall gravitational potential energy of the system.
B. The force of gravity and its distribution across the Earth
While gravity is responsible for the overall shape of the Earth, it is not evenly distributed across the entire planet. The force of gravity is slightly stronger at the poles compared to the equator. This variation in gravitational force is due to the Earth’s rotation. The rotation causes a slight bulge at the equator, resulting in a centrifugal force that counteracts gravity to some extent, making gravity weaker at the equator.
Moreover, local variations in Earth’s composition, such as the distribution of dense materials, can also cause variations in the gravitational force. These variations create gravitational anomalies where the force of gravity is slightly stronger or weaker than the average. Scientists can map these anomalies using specialized instruments, which provide insights into the Earth’s internal structure.
Despite these variations, the force of gravity is still very strong across the Earth’s surface. It is this force that prevents water from falling off the Earth. Gravity acts as an invisible glue, holding everything firmly to the Earth’s surface.
In conclusion, gravity is intimately linked to the shape of the Earth. Its force pulls objects towards the center and determines the overall spherical shape. However, the force of gravity is not evenly distributed, causing slight variations in different regions. Nonetheless, gravity’s influence is vital in keeping objects, including water, firmly on the Earth’s surface. Understanding these concepts is crucial for comprehending various phenomena on our planet, such as the water cycle, ocean tides, and the stability of the planetary system.
Gravity and Water
A. Why water doesn’t fall off Earth’s surface
Water is a fundamental element for life on Earth, and one might wonder why it does not simply fall off the Earth’s surface due to the force of gravity. The answer lies in the concept of gravity and its relationship with the shape and mass of the Earth.
Gravity is the natural force that pulls objects towards each other. In the case of the Earth, its enormous mass creates a gravitational field that attracts all objects towards its center. This gravitational force pulls everything on the Earth, including water, towards its core.
One might think that the round shape of the Earth would cause water to flow towards the bottom, leading to a flat surface with water only at the lowest point. However, the Earth’s gravitational force acts equally on all parts of the planet’s surface, including the water. This means that the force pulling the water downwards is counteracted by an equivalent force pushing the water upwards, resulting in a balanced distribution of water across the Earth’s surface.
B. Influence of gravity on water’s behavior
Gravity not only prevents water from falling off the Earth but also plays a crucial role in the behavior of water. The force of gravity affects water in multiple ways, including its ability to retain its shape and flow.
Gravity ensures that water maintains its liquid state on the Earth’s surface. Unlike gases, which can escape into space due to their low mass, water molecules are more attracted to each other than to the molecules in the atmosphere. The force of gravity keeps the water molecules together and prevents them from vaporizing and escaping into the atmosphere.
Furthermore, gravity determines the flow of water on Earth. It causes water to flow from higher to lower elevations, creating rivers, streams, and waterfalls. Gravity also influences the formation and behavior of bodies of water such as lakes, seas, and oceans, as they seek to find their equilibrium within the Earth’s gravitational field.
In summary, gravity is the force that prevents water from falling off the Earth’s surface. The Earth’s rounded shape, combined with the distribution of gravitational force across its surface, ensures that water remains evenly spread. Gravity also influences water’s ability to flow and retain its liquid state, shaping Earth’s hydrological systems and playing a vital role in supporting life as we know it.
Gravity’s Role in Water Cycle
A. Overview of the water cycle
The water cycle, also known as the hydrologic cycle, is a continuous process through which water circulates on Earth. It involves various stages, including evaporation, condensation, precipitation, and runoff. The water cycle is driven by the energy from the sun and plays a crucial role in maintaining Earth’s water supply.
B. Role of gravity in different stages of the water cycle
Gravity is a fundamental force that influences the movement and behavior of water during different stages of the water cycle. It plays a significant role in the following ways:
1. Evaporation: When the sun’s energy heats up water bodies like oceans, lakes, and rivers, the water molecules gain energy and transform into water vapor. This process is known as evaporation. The gravitational force on Earth holds the water vapor close to the surface, preventing it from escaping and drifting into space.
2. Condensation: As water vapor rises into the atmosphere, it cools down and condenses into tiny droplets or ice crystals. These droplets form clouds. Gravity plays a role in the condensation process by causing the water droplets to coalesce and fall as precipitation when they reach a certain size and weight.
3. Precipitation: Under the influence of gravity, the accumulated water droplets or ice crystals in clouds grow larger and eventually become too heavy to remain suspended in the atmosphere. Gravity pulls the precipitation downwards, causing it to fall as rain, snow, sleet, or hail, depending on the temperature.
4. Runoff: Gravity also plays a crucial role in the movement of water on the Earth’s surface. After precipitation, water eTher infiltrates the soil or flows over the land as runoff. Gravity acts as a guiding force, causing water to flow downhill and ultimately find its way back to oceans, lakes, or other bodies of water.
Overall, gravity is essential in maintaining the continuous circulation of water during the water cycle. It ensures that water stays within Earth’s atmosphere and follows a specific path, allowing for the sustainable distribution of freshwater resources across the planet.
In conclusion, gravity’s role in the water cycle is vital for the continuous availability of freshwater on Earth. It influences water’s behavior during evaporation, condensation, precipitation, and runoff, ensuring that water remains within Earth’s atmosphere and cycles back to its sources. Understanding the relationship between gravity and the water cycle is crucial for studying Earth’s ecosystems, weather patterns, and global water resources.
Gravity and Ocean Tides
A. Relationship between gravity and ocean tides
Gravity plays a crucial role in creating ocean tides, which are the regular rise and fall of sea levels along coastlines around the world. The gravitational forces exerted by the Moon and the Sun are primarily responsible for the formation of tides.
The Moon’s gravitational pull is more significant in comparison to the Sun, even though the Sun is much larger and farther away. This is due to the Moon being much closer to the Earth. The gravitational force from the Moon causes a bulge in the ocean waters on the side of the Earth nearest to the Moon. At the same time, an opposing bulge is created on the side of the Earth furthest from the Moon. These bulges of water imbalance create a tidal cycle.
B. Explanation of high and low tides based on gravity
High tide occurs when the ocean waters rise to their highest level along the coastline, while low tide occurs when the waters recede to their lowest level. These tidal changes occur twice a day and are caused by the gravitational pull of the Moon and the Sun.
When the Moon is directly overhead or on the opposite side of the Earth, it creates a high tide called the “spring tide.” During a spring tide, the gravitational forces of the Moon and the Sun combine, resulting in the highest tidal range.
Conversely, during the Moon’s first and third quarter positions (when it forms a right angle with the Earth and the Sun), the gravitational forces of the Moon and the Sun counteract each other, leading to the lowest tidal range. This is known as a “neap tide.”
It is important to note that while gravity is the primary force driving tides, other factors such as the Earth’s rotation, bathymetry (ocean floor topography), and coastal features can also influence the height and timing of tides.
The understanding of the relationship between gravity and ocean tides is not only crucial for navigational purposes but also for various ecological processes and human activities that rely on tidal patterns, such as fishing, coastal development, and harnessing tidal energy.
In conclusion, gravity’s influence on ocean tides is a fascinating demonstration of the interplay between celestial bodies and the Earth. By understanding the gravitational forces at work, scientists can accurately predict and explain the ebb and flow of tides, contributing to our overall understanding of the dynamic nature of our planet.
Gravity and the Atmosphere
A. Interaction between gravity and Earth’s atmosphere
Gravity plays a crucial role in the behavior and structure of our planet’s atmosphere. It is responsible for holding the atmosphere close to Earth’s surface and preventing it from escaping into space. The force of gravity pulls the molecules of gases, such as nitrogen, oxygen, and carbon dioxide, towards the Earth’s center, creating a layered structure with denser gases at lower altitudes.
As the Earth’s gravitational force is strongest near its surface, the majority of the atmospheric gases are concentrated in the lower regions, closer to the ground. This concentration decreases as we move higher into the atmosphere. The interaction between gravity and the atmosphere creates distinct atmospheric layers, including the troposphere, stratosphere, mesosphere, and thermosphere.
B. How gravity contributes to atmospheric pressure
Gravity also plays a significant role in the creation of atmospheric pressure. Atmospheric pressure is the force exerted by the weight of the atmosphere on a unit area of the Earth’s surface. The gravitational force acts on the molecules of gas in the Earth’s atmosphere, causing them to be pulled towards the Earth’s surface.
The weight of the air above a specific area exerts pressure on the air molecules below, creating atmospheric pressure. As we move closer to the Earth’s surface, the weight of the air above increases, resulting in higher atmospheric pressure. This relationship between gravity and atmospheric pressure is crucial for maintaining the balance and stability of the Earth’s atmosphere.
Understanding the interaction between gravity and the atmosphere is vital for various atmospheric phenomena. It influences weather patterns, air circulation, and the distribution of heat and moisture across the planet. Gravity’s influence on atmospheric pressure determines the behavior of air masses, which in turn affects the formation of weather systems such as high and low-pressure systems, fronts, and storms.
In conclusion, gravity has a significant impact on the Earth’s atmosphere. It keeps the atmosphere close to the Earth’s surface, preventing it from dissipating into space. Additionally, gravity contributes to the creation of atmospheric pressure, which plays a crucial role in governing weather systems and atmospheric phenomena. By understanding the relationship between gravity and the atmosphere, scientists can better comprehend and predict weather patterns and the behavior of our planet’s vital life-sustaining envelope.
Gravity and Earth’s Magnetic Field
A. Connection between gravity and Earth’s magnetic field
Gravity is not only responsible for keeping objects on Earth’s surface, but it also plays a crucial role in the formation and maintenance of the Earth’s magnetic field. The connection between gravity and the magnetic field lies in the core of the Earth.
The Earth’s core consists of two main components: the inner core and the outer core. The inner core is solid and primarily composed of iron and nickel, while the outer core is liquid. The movement of the liquid outer core generates electric currents, which in turn produce the Earth’s magnetic field.
Gravity is involved in this process through the concept of convection. Convection is the transfer of heat through the movement of a fluid. In the case of the Earth’s core, heat from the inner core is transferred to the outer core, causing the fluid to rise. As the fluid rises, it cools and sinks back down in a continuous cycle.
This movement of the fluid creates convection currents within the Earth’s core. These convection currents generate electric currents due to the motion of charged particles, mainly electrons. The interaction between these electric currents and the Earth’s rotation produces a magnetic field around the planet.
Gravity is crucial in maintaining the convection within the core. The force of gravity pulls the denser, cooler fluid back down, allowing the cycle to continue. Without gravity, the convection currents would not occur, and the Earth would not possess a magnetic field.
B. Explanation of the role of gravity in the formation of the magnetic field
Gravity’s role in the formation of the Earth’s magnetic field can be understood through the concept of self-sustaining dynamo. A dynamo is a process that converts mechanical energy into electrical energy. In the case of the Earth’s magnetic field, the dynamo effect is driven by the interaction of gravity and the movement of the fluid within the core.
As the fluid in the outer core rises and falls due to convection, it generates electric currents. These electric currents, in turn, produce a magnetic field. The magnetic field generated reinforces the motion of the fluid and sustains the dynamo effect.
Gravity ensures that the convection within the core continues, providing the necessary movement of the fluid to maintain the magnetic field. The force of gravity acting on the denser, cooler fluid drives it downwards, while the buoyancy force pushes the lighter, warmer fluid upwards. This continuous cycle sustains the convection, electric currents, and ultimately, the Earth’s magnetic field.
In summary, gravity is not only essential for keeping objects on Earth’s surface but also plays a significant role in the formation and maintenance of the Earth’s magnetic field. The convection currents driven by gravity within the Earth’s core generate electric currents, which produce the magnetic field around the planet. Without gravity, the convection and electric currents would cease, resulting in the absence of the Earth’s magnetic field. Understanding the relationship between gravity and the Earth’s magnetic field helps to unravel the intricate mechanisms that shape our planet’s dynamics.
Gravitational Anomalies on Earth
A. Exploration of areas with gravitational anomalies
Gravitational anomalies, also known as gravity anomalies, are variations in the Earth’s gravitational field strength that deviate from the expected normal values. These anomalies have been extensively studied by scientists and have provided valuable insights into the composition and structure of our planet.
Gravity anomaly measurements are typically conducted using a device called a gravimeter, which is capable of detecting even the slightest changes in gravitational forces. By analyzing variations in gravitational acceleration, scientists can identify regions where the Earth’s density or mass distribution differs from what is considered normal.
One well-known example of a gravitational anomaly is the Bermuda Triangle. This region located in the western part of the North Atlantic Ocean has gained notoriety due to numerous reports of unexplained disappearances of ships and aircraft. Some theories suggest that gravitational anomalies in the area could be responsible for these incidents, although scientific evidence supporting this claim is limited.
Another fascinating gravitational anomaly is found in the Hudson Bay area in Canada. Scientists have discovered that this region has lower-than-normal gravitational values compared to surrounding areas. The cause for this anomaly lies in the retreat of glaciers that once covered the region during the last ice age. As the glaciers melted, the Earth’s crust rebounded, resulting in a redistribution of mass and creating a gravitational anomaly.
B. Causes and effects of these anomalies
Gravitational anomalies can have various causes, including variations in subsurface geological structures, differences in rock density, and the presence of mineral resources. In some cases, human activities such as mining and extraction of natural resources can also contribute to localized gravitational anomalies.
These anomalies can have significant effects on both scientific research and practical applications. For example, in the field of geophysics, studying gravity anomalies helps in mapping and understanding the geological features of an area. By analyzing the anomalies, scientists can identify potential mineral deposits, oil and gas reservoirs, or even underground water sources.
Gravitational anomalies also play a crucial role in navigation and satellite-based positioning systems. These anomalies can affect the accuracy of GPS measurements, especially in regions where the gravitational field strength deviates significantly from the expected norm. Precise mapping and correction of these anomalies are essential for maintaining the reliability of global positioning systems.
In conclusion, gravitational anomalies offer valuable insights into the underlying geological and geophysical characteristics of the Earth. By studying these anomalies, scientists can gain a better understanding of the planet’s structure and composition. Furthermore, accurate mapping and correction of these anomalies are crucial for various applications, including resource exploration, navigation, and satellite-based positioning systems. However, more research is still needed to fully comprehend the causes and effects of these gravitational anomalies and their implications for our understanding of the Earth and its processes.
Gravitational Forces in Space
A. Comparison of gravity on Earth and in space
In this section, we will explore the differences between gravity on Earth and in space. While gravity plays a crucial role in keeping objects on Earth’s surface, its behavior and effects change when we venture beyond our planet.
On Earth, gravity always pulls objects toward the center of the planet. The strength of gravity is determined by both the mass of the planet and the distance between the object and the planet’s center. However, in space, the force of gravity varies depending on the mass and proximity of celestial objects.
The gravity on Earth’s surface is approximately 9.8 m/s^2, which means that objects experience a constant acceleration of 9.8 meters per second squared when falling freely. This acceleration is what causes objects to fall downward when dropped.
In space, gravity differs from planet to planet, depending on their mass. For example, the gravity on the Moon is about one-sixth of the gravity on Earth. Astronauts on the Moon experience a much lighter gravitational pull, allowing them to leap higher and lift heavy objects with relative ease. On the other hand, the gravity on massive gas giants like Jupiter is significantly stronger than that on Earth.
B. How gravity affects objects and motion in space
Gravity in space affects objects and their motion in various ways. First and foremost, it is the force that keeps celestial bodies like planets, moons, and satellites in their orbits around larger objects. For example, the gravitational pull of the Sun keeps all the planets in our solar system looping around it.
In addition to orbital motion, gravity can cause objects to collide and merge together. When two celestial bodies come close enough due to the gravitational attraction between them, they can eTher form a binary system or collide and merge to form a larger object. This process has played a significant role in the formation and evolution of the universe.
Gravity also plays a crucial role in the phenomenon of gravitational lensing, where a massive object bends the path of light passing near it. This effect has allowed scientists to observe and study distant galaxies and other cosmic objects that would otherwise be too faint or obscured to detect.
Understanding the behavior of gravity in space is fundamental to space exploration and the study of the universe. It allows scientists and astronomers to predict the movements of planets and other objects, navigate spacecraft, and explore the mysteries of our cosmos.
In conclusion, the difference in gravity between Earth and space has far-reaching implications. While gravity on Earth keeps objects grounded, gravity in space shapes the movements of celestial bodies, causes collisions and mergers, and influences the behavior of light. By studying these gravitational forces, we deepen our understanding of the universe and our place within it.
## XGravity and Planetary Movement
### A. Gravity’s role in keeping planets in orbit
Gravity plays a crucial role in the movement and stability of planets within our solar system. The force of gravity between the Sun and the planets keeps them in their respective orbits. This gravitational attraction between celestial bodies is what prevents the planets from drifting off into space.
According to the laws of gravitation formulated by Sir Isaac Newton, every object in the universe attracts every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between their centers. In the case of planetary movement, the gravity of the Sun is what keeps the planets in their elliptical orbits.
Each planet’s orbit is a delicate balance between the gravitational pull of the Sun and the planet’s own inertia or tendency to move in a straight line. This relationship between gravity and inertia results in a stable orbit around the Sun. If the force of gravity were weaker, the planet would move away from the Sun, while a stronger force of gravity would cause the planet to spiral into the Sun.
### B. The effect of gravity on the stability of the solar system
Gravity not only keeps individual planets in their orbits but also maintains the overall stability and structure of the solar system. The gravitational interaction between the Sun and the planets creates a dynamic equilibrium that ensures the planets remain in relatively stable positions.
The gravitational forces exerted by the planets on each other also contribute to the stability of the solar system. While the Sun’s gravity dominates, the gravity between the planets has a subtle influence. These gravitational interactions can cause minor perturbations in their orbits, resulting in variations in their positions and orbital parameters over time.
One remarkable example of gravitational stability is the Kuiper Belt, a region beyond Neptune’s orbit that contains numerous small celestial bodies. Despite the gravitational influence of the gas giants like Jupiter and Neptune, the objects within the Kuiper Belt remain relatively stable and do not collide with each other or get ejected from the solar system.
Understanding the role of gravity in planetary movement is of great significance as it enables scientists to accurately predict the positions and motions of celestial bodies. It allows us to explore the cosmos, plan space missions, and deepen our understanding of the universe.
Overall, gravity plays a crucial role in keeping planets in their orbits and ensuring the stability of the solar system. Its influence extends far beyond our planet, shaping the movement and behavior of objects in the vast expanse of space.
13. Conclusion

Furthermore, we have examined the historical understanding of the Earth’s shape and the evidence supporting its round shape. The combination of scientific observations, such as the curvature of the Earth’s shadow during lunar eclipses and photographs of Earth from space, has solidified our understanding of the Earth’s shape.
B. Final thoughts on the relationship between gravity and water staying on Earth’s surface
One of the intriguing aspects of gravity’s influence is its effect on water. We have explored why water doesn’t fall off the Earth’s surface despite it being a liquid. Thanks to gravity, which acts as a force pulling objects towards the center of the Earth, water is able to stay on Earth’s surface and not float off into space. This force of gravity keeps the oceans, rivers, lakes, and even the water in the atmosphere firmly grounded.
Gravity’s role extends beyond simply holding water on the Earth’s surface. It also plays a fundamental role in the water cycle, in which water evaporates, condenses, and precipitates. Gravity helps regulate the movement of water throughout the cycle, ensuring a continuous supply of freshwater on Earth.
Additionally, gravity influences another fascinating natural phenomenon: ocean tides. The gravitational pull of the moon and the sun creates tidal bulges, resulting in high and low tides. The relationship between gravity and ocean tides is a complex interplay that is still being studied and understood by scientists.
In conclusion, gravity is a fundamental force that has a profound impact on our daily lives. From keeping our feet firmly on the ground to regulating the water cycle and creating ocean tides, gravity shapes many aspects of the Earth. Understanding the relationship between gravity and Earth’s shape is not only academically significant but also crucial for a deeper appreciation of the world around us. So the next time you see a glass of water on your table, remember that gravity is the force keeping it from falling off the Earth.
