ESS2.2 Review Challenge

The image above shows part of an ocean current in the Pacific Ocean. The blue line represents the motion of deep, cool water. The red line represents the motion of warm surface water. What most likely causes the current to behave as shown in the image?

• When the deep water is cooled, it loses energy and becomes denser.

• When the surface water is heated by the Sun, it becomes denser.

• When the cold water evaporates, less dense water rises to take its place.

• When the water is heated, it becomes less dense and rises

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 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.
