Complete question:

Due to the Earth's shape and orientation, areas near the Equator receive the greatest amount of energy from the Sun. Ocean currents

A. move only away from the equator as a result.

B. help to distribute this energy by warming other regions of the globe.

C. move only toward the equator as a result.

D. keep this energy concentrated in one region of the globe

B. help to distribute this energy by warming other regions of the globe.

Explanation:

Heat it gained in equatorial latitudes and lost in higher latitudes. Winds and marine currents redistribute the heat around the earth. The ocean clime is influenced by winds, and show a lower thermic amplitude than continental climes due to a bigger redistribution of heat by the currents.  

There exist horizontal water movements that are produced by the action of different winds on the ocean surface. Superficial winds, influenced by the Coriolis effects, are responsible for most of the marine currents.

Trade winds push the water surface forward western direction in the equator, while western winds produce currents that move water to the east at higher latitudes. By the Coriolis effect, water masses are deviated to the west or the east, depending on the hemisphere, and result in large clockwise circular turns in the Northern Hemisphere, and in the opposite direction in the Southern Hemisphere.

Warmer currents travel from the tropics, along the continental margins, carrying warm water to higher latitudes, and as they do so, these water masses get cooler, producing cold currents.

There also exist vertical water movements, such as the ascendant “upwelling” currents that transport cold water with nutrients from the bottom to the surface. Through trade winds at higher latitudes, surface water is diverted out to sea, making a place for the ascent of cold water from the deep. At tropical latitudes, descendent “downwelling” currents occur. Dense cold water from the poles descends as they get in touch with warmer water from lower latitudes.
