Question

In your own words, how do the three (3) major processes of heat

transfer affect the temperature of the Earth? ​

Answer 1

The temperature of the Earth is maintained by the three major processes of heat which are conduction, convection and radiation.

• Conduction can easily be described as the transfer of heat energy from one substance to another or within the same object.
• It is through conduction that the ground heats the air.
• Convection can easily be described as the transfer of heat energy in a fluid.
• Air in the atmosphere acts as a fluid and through convection the warm air rises.
• Radiation is the transfer of heat energy by electromagnetic radiation through space.
• It is through radiation that the Sun heats the Earth ground.

Answer 2

Explanation:

It is through conduction that the ground heats the air. Convection can easily be described as the transfer of heat energy in a fluid. Air in the atmosphere acts as a fluid and through convection the warm air rises. Radiation is the transfer of heat energy by electromagnetic radiation through space.
