Part of the sun's 3that reachesthe earth's surface is absorbed by land and water as heat. The earth's surface then releases heat back to the atmosphere.

The sun releases heat to the earth in the form of electromagnetic waves. The earth releases heat into the atmosphere in the form of long wave infrared radiation.

Explanation:

As stated in the question above, part of the heat from the sun's rays is absorbed by the earth in the form of electromagnetic waves. The earth in turn also releases this energy, which is partly absorbed by the atmosphere (through water vapor and greenhouse gases) and is partly released into space. The difference is that the heat emitted by the earth takes the form of long wave infrared radiation
