What are protective functions of the atmosphere?

The atmosphere serves several protective functions, including filtering harmful solar radiation, particularly ultraviolet rays, thus shielding living organisms from damage. It also regulates temperature by trapping heat through the greenhouse effect, maintaining a stable climate conducive to life. Additionally, the atmosphere protects the Earth from space debris by burning up smaller meteoroids upon entry, preventing them from reaching the surface. Lastly, it plays a critical role in weather patterns, which helps sustain ecosystems and biodiversity.
