Question

how does atmosphere not allow heat to escape in nights​

Answer 1

There are some gases in the atmosphere which trap the heat escaping from the Earth and stop it from travelling back into space. These gases are called greenhouse gases. The glass in a greenhouse has a similar effect on the Sun's rays and so it is called the Greenhouse Effect.
