Answer 1

Earth is warmed by the Sun. However, while it is turned to Sun. But when it is in the shadow of itvery good. cools rapidly. The Earth'satmosphere smoothes fluctuations in temperature of the Earth surface. And in space emits about the same amount of energy due tothermal radiation, and how much gets. It is therefore clear winter nights colder
than clouds partly cloudy-delay back and reflect infrared radiation.
