IStratosphere and Its Altitude
A. Defining the stratosphere and its characteristics
The stratosphere is a layer of the Earth’s atmosphere located above the troposphere and below the mesosphere. It is characterized by a relatively stable temperature profile, with temperatures increasing as altitude increases. This temperature profile is a result of the presence of the ozone layer, which absorbs and reflects a significant portion of the Sun’s ultraviolet radiation.
The stratosphere is an important part of the Earth’s atmosphere because it plays a crucial role in protecting life on Earth. The presence of the ozone layer in the stratosphere helps to shield the Earth’s surface from harmful ultraviolet radiation, which can cause skin cancer and other health issues.
B. Average altitude of the stratosphere (7-31 miles above sea level)
The average altitude of the stratosphere is approximately 7-31 miles above sea level. This altitude range varies depending on factors such as latitude and season. Near the equator, the stratosphere starts at a higher altitude, while at the poles it starts at a lower altitude.
The boundary between the troposphere and the stratosphere, known as the tropopause, is located at approximately 7-12 miles above sea level. Above the tropopause, the temperature starts to increase due to the presence of the ozone layer.
The top of the stratosphere, known as the stratopause, is located at approximately 31 miles above sea level. At this altitude, the temperature stops increasing and begins to decrease again in the mesosphere.
Understanding the altitude range of the stratosphere is important in the field of aviation, as it helps determine the potential altitude limits for aircraft and other technologies. It also provides valuable information for scientists and researchers studying the Earth’s atmosphere and climate.
In summary, the stratosphere is a significant layer of the Earth’s atmosphere, located above the troposphere and below the mesosphere. It is characterized by a stable temperature profile and plays a crucial role in protecting life on Earth. The average altitude of the stratosphere ranges from 7 to 31 miles above sea level and varies depending on factors such as latitude and season.
