Option D: Clouds reflect sunlight back into space, affecting the Earth's temperature. This is a natural process.

10. Which climate condition generally results from both an increase in distance from the equator and an increase in elevation above sea level?

Correct Answer: Correct answer is: (A) Cooler temperatures.

Exam Relevance: AP Environmental Science, SAT Subject Test in Earth Science, GRE Subject Test in Geology

Difficulty: Easy

Concept notes: As distance from the equator increases, temperatures generally decrease due to the angle of sunlight and the longer path the sunlight must travel through the atmosphere. Similarly, as elevation increases, temperatures also decrease because the atmosphere becomes thinner and less able to retain heat.

Common Mistakes: A common misunderstanding is that elevation and distance from the equator have no significant impact on temperature, or that they might increase temperature instead of decreasing it.

Explanations: As distance from the equator increases, the angle of sunlight becomes more oblique, leading to less direct solar radiation and cooler temperatures. Additionally, as elevation increases, the air becomes thinner and less able to retain heat, resulting in cooler temperatures. Therefore, both factors contribute to cooler temperatures.

Option Analysis:

Option A: Correct. Cooler temperatures result from both increased distance from the equator and increased elevation above sea level.
Option B: Incorrect. Warmer prevailing winds are not a general result of increased distance from the equator or increased elevation.
Option C: Incorrect. Increased precipitation is not a general result of increased distance from the equator or increased elevation.
Option D: Incorrect. Increased air pressure is not a general result of increased distance from the equator or increased elevation.
