Describe the air on the windward side of a mountain.

• dry

• hot

• moist

• cold

Why does a convection current begin over the equatorial region?

• Equatorial latitudes receive more direct sunlight, and this energy is re-radiated from the land as it cools in the form of cooler air, which falls.

• Equatorial latitudes receive indirect sunlight, and this energy is re-radiated from the land as it cools in the form of cooler air, which rises.

• Equatorial latitudes receive more direct sunlight, and this energy is re-radiated from the land as it cools in the form of warmer air, which rises

• Equatorial latitudes receive indirect sunlight, and this energy is re-radiated from the land as it cools in the form of warmer air, which falls.

The diagram shows the movement of air at the beach on a hot day.

Which statement about air movement in the diagram is true?

• Air movement over the land and water is caused by unequal heating of Earth's surface.

• Air over water cools more quickly than air over land, causing rising and falling air masses.

• The tides and currents in the ocean affect the movement of air masses above both land and water.

• Energy from organisms on land and water have an effect on the movement of air masses.

A student examines a map showing the flow of ocean currents throughout the world.

What would be the major consequence if global current circulation stops?

• The climates of the coastal equatorial regions would become colder and wetter, and the climates of the coastal polar regions would become warmer and dryer.

• The climates of the coastal equatorial regions would become hotter and and the climates of the coastal polar regions would become colder

• The climates of the coastal equatorial regions would become hotter and wetter, and the climates of the coastal polar regions would become colder and dryer.

• The climates of the coastal equatorial regions would become colder and drier, and the climates of the coastal polar regions would become warmer and wetter.
