7. Which region receives the least amount of solar radiation?

Correct Answer: Correct answer is: (B) Polar region.

Exam Relevance: GRE, MCAT, GATE, SAT

Difficulty: Easy

Concept notes: The polar regions receive the least amount of solar radiation due to their high latitude and the angle at which sunlight strikes the Earth's surface.

Common Mistakes: A common misunderstanding is that the equatorial region receives the least solar radiation because it is closer to the sun. However, the equatorial region actually receives the most solar radiation due to the direct angle of sunlight.

Explanations: The polar regions receive the least amount of solar radiation because the sun's rays strike the Earth's surface at a very shallow angle. This results in the solar energy being spread over a larger area, leading to lower intensity. Additionally, the long nights during the polar winter further reduce the amount of solar radiation received.

Option Analysis:

Option A: The equatorial region receives the most solar radiation due to the direct angle of sunlight.
Option B: The polar region receives the least solar radiation due to the shallow angle of sunlight and long periods of darkness.
Option C: The sub-tropical region receives moderate amounts of solar radiation, more than the polar regions but less than the equatorial regions.
Option D: The temperate region receives moderate amounts of solar radiation, more than the polar regions but less than the equatorial regions.

Mnemonic: Polar = Cold = Less Sun
