What is the main function of the atmosphere?

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation. Up to about 80 km, the composition of atmosphere is highly uniform; therefore, the term homosphere is applied.
