ESS2.2 Atmospheric Convection Quiz -H

Why is the surface of the earth unevenly heated?

• When the sun’s energy is transferred to the earth’s surface, it hits the area around the north and south poles most directly, while hitting the area around the equator at an angle.

• When the sun’s energy is transferred to the earth’s surface, it hits the area around the equator most directly, while hitting the areas around the north and south poles at an angle.

• The earth’s surface is evenly heated.

• None of the above

Which answer choice correctly describes the movement of air on Earth?

• Warm air rises from the equator and moves toward the poles because it is less dense.

• Warm air rises from the equator and moves toward the poles because it is more dense.

• Warm air rises from the north and south poles, then sinks toward the equator because it is less dense.

• Warm air rises from the north and south poles, then sinks toward the equator because it is more dense.

Which answer choice correctly describes a convection cell? ( 2 answers)

• Warm air rises, then cools and sinks.

• Cool air rises, then warms up and sinks.

• Warm air rises because its molecules are spread out (less dense).

• Warm air rises because its molecules are packed tightly together (more dense).

Which answer choice correctly describes a

Hadley Convection Cell? (2 answers)

• The Hadley cell causes rainforests and

  deserts to form.

• The Hadley cell causes temperate deciduous

  forests to form.

• Warm air rises from the equator, cools, and sinks at about 30 degrees north and south of the equator.

• Warm air rises from 30 degrees north and south,

  cools, then sinks near the poles.

Which answer choice correctly describes convection cells?

• There are 2 major convection cells, one in the northern hemisphere and one in the southern hemisphere.

• There are 4 major convection cells due to the Coriolis effect.

• There are 5 major convection cells due to the Coriolis effect.

• There are 6 major convection cells, three above the equator, and three below the equator.

How do convection cells function?

• Warm air rises from the earth’s surface, cools in the atmosphere, and then sinks back to the earth’s surface.

• Cool air rises from the earth’s surface, warms up in the atmosphere, and then sinks back to the earth’s surface.

• Convection cells only occur above the equator

• Convection cells only occur below the equator.

Which answer choice correctly describes the Hadley Cell? (Choose ALL that apply.)

• Warm air rises from the equator causing deserts to form along the equator.

• Warm air rises from the equator, causing water vapor to condense into clouds in the atmosphere above the equator.

• Cool air sinks at the equator causing rainforests to form.

• Cooler air sinks at the latitudes above and below the equator. This air is dry and results in deserts.

Students are demonstrating the movement of wind. In Step 1, they blow up a balloon, trying to make it as round as possible. In Step 2, they draw a line around the middle of the balloon to represent the equator. In step 3, one student spins the balloon. While the balloon spins, another student draws a line from the middle of the balloon to the top.

In which two ways can this model represent the Coriolis effect? ( 2 answers)

• Warm air rising causes cooler air to sink to the surface.

• Rotation of Earth causes the wind to appear to curve.

• Wind at the equator is denser than wind at the poles.

• Cool air flows faster than warmer air as it moves across Earth.

• The amount the wind appears to curve depends on the speed of Earth’s rotation.
