Expert Answer
The sun is an extremely hot object. It emits heat radiations in all directions. These radiations travel through vacuum between the sun and the earth at a very high speed and reach the earth. When the sun's radiations fall on the earth and its objects, they receive heat energy and hence get heated. Thus, the sun's heat reaches the earth by the process of radiation.
