Question
If the earth did not have an atmosphere it would become intolerable cold. Why?
✓
Answer
The lower layer of earth's atmosphere reflects infra-red radiations from earth back to the surface of the earth. So the heat radiation received by the earth from the sun during day time are trapped by the atmosphere. Therefore, if the earth did not have atmosphere, its surface would become too cold to tolerate.
