• The atmosphere is primarily made of water vapor.

How does the atmosphere protect the Earth from harmful radiation?

• The atmosphere protects the Earth from harmful radiation by absorbing UV radiation through the ozone layer and scattering other harmful rays.

• The atmosphere generates harmful radiation to protect the Earth.

• The atmosphere reflects all radiation back into space.

• The atmosphere has no effect on radiation from the sun.
