Sun is the primary source of heat and energy on Earth's surface. What type of heat transfer mostly occurs on Earth's surface?

The primary type of heat transfer that occurs on Earth's surface is radiation. Here's a step-by-step explanation:

1. The Sun emits energy in the form of electromagnetic waves. This energy travels through the vacuum of space towards Earth.

2. When this energy reaches Earth, it is absorbed by the Earth's surface, heating it up. This is the process of radiation - the transfer of energy through space by electromagnetic waves.

3. The heated Earth's surface then emits some of this energy back into the atmosphere as infrared radiation.

4. Some of this infrared radiation is absorbed by gases in the atmosphere, further heating it. This is known as
