1.

Which explanation accurately describes convection within the ocean?

a)

Earth's mantle heats water at the bottom of the ocean, causing the water to rise toward the surface. The air at the surface cools the water, causing the water to sink

b)

Water near the ocean' surface is heated by air, causing it to sink toward the bottom of the ocean. As the water cools it sinks, causing it to rise back toward the surface

c)

Water near the equator is warmer because of direct sunlight. Water near the poles is cold and dense. Warm water moves toward the poles and cold water moves toward the equator

d)

The sun heats the surface of the water. The deeper the water, the colder it becomes. Warm water sinks and cold water rises

2.

Energy from the sun creates pressure and temperatures differences on Earth's surface, which produce winds. These winds provide energy for the production of-

a)

waves and ocean currents

water cycle and radiation

c)

conduction and water cycle

d)

ocean currents and conduction
