Question

When both incoming and outgoing radiation are balanced, it is called _________.

• A. heat summation
• B. heat balance
• C. heat budget
• D. none of these

Answer 1

The correct option is C heat budget

Sun is the main source of energy for earth. The earth 's surface receives solar energy in form of short-wave solar radiation where it is converted into heat by the process of absorption. The earth sends the same amount of energy back to space in the form of long-wave terrestrial radiation. This balance between the amount of insolation received from the sun and the outgoing terrestrial radiation is known as the earth's heat budget.
