Global Air Circulation Quiz

What is atmospheric pressure?

• The temperature of the air

• The weight of the atmosphere on the surface of the Earth

• The density of air at sea level

• The movement of air in the atmosphere

Where does the Equatorial low-pressure belt occur?

• At the North and South Poles

• At 0 degrees

• At 30 degrees North and South

• At 60 degrees North and South

What type of weather is associated with the Subtropical high-pressure belt?

• Frequent hurricanes and storms

• Cloudless skies and low rainfall

• High rainfall and thunderstorms

• Heavy snowfall and cold temperatures

What occurs at the Subpolar low-pressure belt?

• Cold air descends

• Warm air rises due to cold air convergence

• Stable, cloudless conditions

• High-pressure systems dominate

What is the primary characteristic of the Polar high-pressure belt?

• Frequent thunderstorms

• Cold, dense air descending

• Warm, moist air rising

• High temperatures and humidity

What happens to air at point C in the global circulation model?

• It cools and condenses

• It remains stationary

• It sinks and creates high pressure

• It rises and creates low pressure

What is the ITCZ also known as?

• Subtropical high-pressure belt

• Equatorial low-pressure belt

• Polar front
