a) UNIT 1: Hazardous Earth- Climate change

What are the three circulation cells?

• Desert, Derrel, Polar

• Hadley, Ferrel, Polar

• Hadley, Desert, Polar

• Polar, Equator, Hadley

Why does the equator receive the most solar radiation? (2 reasons)

• Solar radiation travels through thicker atmosphere so more energy is lost.

• Solar radiation travels through less atmosphere so less energy is lost.

• The radiation is dispersed over a larger area making it less concentrated.

• The angle is direct so radiation is concentrated.

Which circulation cell is located closest to the equator?

• Ferrel

• Hadley

• Polar

• Desert

Which circulation cell is primarily responsible for the weather patterns in the mid-latitudes?

• Hadley

• Ferrel

• Polar

• Equatorial

What is the name of the area of intense low pressure at the equator?

• Immediate takeover cooling zone

• Intertropical convergence zone

• Intertropical confluence zone

• International tropical cold zone

How is heat redistributed around the earth? (2 ways)

• Air circulation

• Precipitaion

• Ocean currents

• Orbital changes

Which of the following is not a natural cause of climate change?

• Volcanic eruptions

• Burning fossil fuels

• Sun spots

• Asteroid collisions

Which of the following gases is a major contributor to the greenhouse effect?

• Nitrogen

• Oxygen

• Carbon dioxide

• Argon

Which of the following is a consequence of global warming?

• Decrease in sea levels

• Increase in polar ice caps

• More frequent extreme weather events

• Stabilization of global temperatures

True or false: Low pressure leads to dry and settled weather.

• True

• False
