Air Currents

What is the result of sunlight being spread over a larger surface area at the poles?

• The poles are warmer

• The poles are cooler

• The poles have the same temperature as the equator

• The poles receive more energy

What is the main idea of the section titled "The Sun’s Angle"?

• The Sun's angle affects the amount of energy an area gets

• The Sun's angle is always the same

• The Sun's angle does not affect the Earth's surface

• The Sun's angle only affects the poles

• Movement of air from high pressure to low pressure

• Movement of air from cold areas to warm areas

• Movement of air from warm areas to cold areas

What is the role of the second cell in the global wind belt model?

• It is a convection cell

• It is driven by the other two cells

• It moves air from the equator to the poles

• It moves air from the poles to the equator

Where do polar easterlies originate?

• Near the equator

• Between 30°N and 30°S

• Near the North Pole and the South Pole

• Between 30°N and 60°N

What happens to air at about 30°N and 30°S latitude?

• It rises and creates low pressure

• It cools and sinks, creating high pressure

• It moves rapidly, creating strong winds

• It remains still, creating no pressure
