Our atmosphere acts as a greenhouse. Explain.

The atmosphere acts as a greenhouse by trapping and retaining heat energy from the Sun, similar to how a greenhouse retains heat to create a warmer environment for plants.

The greenhouse gases in the atmosphere allow the infrared rays from the Sun to penetrate the Earth but do not allow the heat radiated by the heated Earth to penetrate back into space. Thus, they act like a blanket around the Earth.

By trapping heat, the atmosphere helps to regulate the Earth's temperature and maintain suitable conditions for life.
