Chapter 8: Solar Radiation Heat Balance and Temperature — Important Questions & Answers
What is the term used for the incoming solar radiation received by the Earth's surface?
- A. Insolation
- B. Terrestrial radiation
- C. Albedo
- D. Heat budget
Answer: A. Insolation
Insolation means incoming solar radiation received by the Earth. It is the main source of energy for weather and climate.
Insolation means incoming solar radiation received by the Earth. It is the main source of energy for weather and climate.
Which latitude receives the maximum annual insolation?
- A. 90° N/S
- B. 60° N/S
- C. 0°
- D. 23.5° N/S
Answer: C. 0°
The Equator receives the Sun's rays more directly throughout the year, so it generally gets the maximum annual insolation.
The Equator receives the Sun's rays more directly throughout the year, so it generally gets the maximum annual insolation.
Why do places near the Equator generally remain warmer than polar regions?
- A. They receive slanting rays of the Sun
- B. They receive direct rays of the Sun throughout the year
- C. They are farther from the atmosphere
- D. They have no seasons
Answer: B. They receive direct rays of the Sun throughout the year
Near the Equator, the Sun’s rays are more direct and concentrated over a smaller area, producing greater heating.
Near the Equator, the Sun’s rays are more direct and concentrated over a smaller area, producing greater heating.
Which of the following correctly arranges the surfaces in decreasing order of absorption of solar radiation?
- A. Fresh snow > dry sand > black soil
- B. Black soil > dry sand > fresh snow
- C. Dry sand > black soil > fresh snow
- D. Fresh snow > black soil > dry sand
Answer: B. Black soil > dry sand > fresh snow
Darker surfaces absorb more solar radiation, while fresh snow reflects most of it because of its high albedo.
Darker surfaces absorb more solar radiation, while fresh snow reflects most of it because of its high albedo.
Which one of the following statements about heat budget is correct?
- A. The Earth receives more heat than it loses at every latitude all year
- B. The tropics have a surplus and the poles have a deficit of heat
- C. The poles have a surplus and the tropics have a deficit of heat
- D. Heat budget is the same as daily temperature range
Answer: B. The tropics have a surplus and the poles have a deficit of heat
The tropics generally receive more heat than they lose, while the poles lose more heat than they receive, creating a heat surplus and deficit respectively.
The tropics generally receive more heat than they lose, while the poles lose more heat than they receive, creating a heat surplus and deficit respectively.
