Global Atmospheric Circulation and Climate Patterns

Multiple Choice

Why is insolation (incoming solar radiation) stronger at the equator than at the poles?

• Because the equator receives more direct sunlight due to the angle of the sun's rays

• Because the equator is closer to the sun

• Because the poles have more clouds

• Because the equator has less atmosphere

Multiple Choice

Which of the following best describes the Hadley Cell?

• Hot air rises at the equator, rains, and sinks dry at 30°

• Cold, dense air sinks at the poles, weak easterlies

• Weaker, pushed by Hadley & Polar cells

• Air circulates only at the poles

Multiple Choice

Which wind belt is primarily associated with the Hadley Cell?

• Trade Winds

• Westerlies

• Polar Easterlies

• Monsoon Winds

Open Ended

Explain how the three major atmospheric cells (Hadley, Ferrell, and Polar) interact to influence global wind patterns and the distribution of deserts and rainforests.

Multiple Choice

What is a common misconception about why deserts form at the equator?

• People think deserts form at the equator because it is hot, but the equator is actually a wet rainforest.

• People think deserts form at the equator because of sinking cold air.

• People think deserts form at the equator due to high albedo.

• People think deserts form at the equator because of the Coriolis effect.
