Question

Explain how the Earth’s atmosphere helps in maintaining a suitable temperature for life to survive on the Earth.

Answer 1

The atmosphere shields life from harmful ultraviolet rays through the ozone layer and absorbs/scatters some incoming solar radiation. It also acts like a blanket: greenhouse gases such as $$\mathrm{CO_2}$$, methane, and water vapour trap outgoing infrared radiation, keeping Earth warm. Winds and water movements distribute heat around the globe, preventing extreme temperatures and making Earth habitable.
