What four things our atmosphere does for us

Our atmosphere keeps the things from space away from earth's surface. Without the atmosphere, the average temperature on Earth would be below freezing!) The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. A thin layer of gas called ozone high up in the atmosphere filters out these dangerous rays. hope this helps!  :)

1.) Without the atmosphere, average temperature on Earth would be freezing! Below zero to be exact!

2.) The atmosphere protects us and animals from dangerous radiation from the Sun. Ultraviolet radiation is basically invisible rays of energy created by the sun.

3.) Also, the atmosphere provides oxygen for humans and animals to breathe and C02 (Carbon dioxide) for plants. 

4.) And lastly, the atmosphere protects us from objects coming towards the earth. 

Hope this helps!
