ES Semester 1 menu Oceans and currents

Solar radiation provides more heat near the equator than near the poles on Earth. The greatest amount of heat is moved away from the equator by…

• ocean currents

• aquatic plants

• surface winds

• tectonic plates

Because water can hold a large amount of heat, which effect do oceans have on nearby land areas?

• They prevent rapid extreme temperature changes.

• They form high-pressure areas that cause magma currents.

• They provide the energy that triggers volcanic events.

• They lower the freezing point of fresh water

Deep ocean currents continually circulate from the warm waters near the equator to the colder waters in other parts of the world. What is the main cause of deep currents?

• Differences in the topography along the ocean floor

• Differences in density of ocean water

• The rotation of Earth on its axis

• Movement of the jet stream

Which statement BEST explains the link between ocean currents and heat from solar radiation?

• The movement of water creates heat.

• Ocean currents circulate heat away from the equator.

• Earth’s internal heat is pushed outward through volcanic activity.

• Land warms as ocean water makes direct contact with land.

The Great Ocean Conveyor Belt shows the flow pattern of deep-sea density currents. Which statement BEST describes an effect caused by these currents?

• They prevent tsunamis from occurring.

• They control low and high tides.

• They influence climate by distributing energy from the Sun.

• They cause hurricanes to move in a counterclockwise direction.

Which statement about the relationship between the ocean and air in the atmosphere is true?

• Ocean currents flow into the atmospheric air.

• The air in the atmosphere stores more heat than the ocean.

• The ocean can hold heat more efficiently than the air.

• Ocean currents can move faster than air or wind currents.
