Answer 1

The atmosphere blocks out harmful rays from the sun. The ozone layer, which lies in the stratosphere 11 to 50 kilometers from the Earth's surface, blocks out many harmful forms of radiation. Without the ozone layer, ultraviolet rays would destroy most life on Earth. Gases in the atmosphere also hold in heat.
