The ability of an igloo to provide shelter and retain heat is essential for survival in these harsh conditions.
B. The quality of the snow used
The quality of the snow used in the construction of an igloo is crucial for its durability. The snow needs to have a high moisture content, as this allows the snow blocks to bond together effectively. Dry and powdery snow is not suitable for building igloos as it doesn’t have the necessary cohesion. In addition to moisture content, the size and shape of the snow crystals also play a role in the strength of an igloo. Larger snowflakes with more complex crystal structures can enhance the adhesive properties of the snow blocks.
C. Design and shape of the igloo
The design and shape of the igloo contribute significantly to its overall durability. Traditionally, igloos are dome-shaped, which allows for even distribution of weight. The rounded shape minimizes the risk of collapsing under heavy snow or strong winds. The curvature of the dome also helps to disperse wind pressure, preventing it from exerting excessive force on the igloo. The entrance of the igloo is often constructed in a way that redirects the wind to minimize exposure and the risk of snow accumulation inside.
The size and height of the igloo can also affect its durability. Smaller igloos tend to be more resilient since they have a smaller surface area exposed to external forces. Additionally, a well-constructed roof with a flat top and a solid supporting central pillar can help distribute the weight evenly, preventing any weak points that could compromise the structure.
Overall, the durability of an igloo depends on various factors related to climate conditions, the quality of the snow used, and the design and shape of the structure. Understanding these factors is crucial for constructing long-lasting igloos that can withstand the challenges of extreme weather conditions.
