Question

What are 3 ways that the atmosphere benifits life on earth?

Answer 1

Here are a few:

1. It lessens the amount of harmful solar radiation from the sun.

2. It provides a holding place for breathable oxygen for animals (or CO2 for plants)

3. It absorbs water vapor, which allows for redistribution of fresh water through rainfall.

4. It traps the sun's warmth - without an atmosphere, the earth would too be hot to survive during the day, and too cold to survive at night.

5. It burns small meteors up before they they reach the earth and hit us in the head.

Answer 2

precipitation is the biggest one; plants use co2 in the atmosphere and give the world oxygen
