Question

What role do seasonal changes in snow and ice cover play in Earth's climate?

Answer 1

Seasonal changes in snow and ice cover play an important role in Earth's climate. Snow and ice reflect sunlight, which helps to regulate the planet's temperature. When there is more snow and ice cover, more sunlight is reflected back into space, leading to a cooling effect. Conversely, when there is less snow and ice cover, less sunlight is reflected, leading to a warming effect.

In addition to their reflective properties, snow and ice also play a role in the global water cycle. During the colder months, snow and ice store water, which is released back into the atmosphere when they melt. This can affect the availability of water for irrigation, drinking, and other purposes.
