Question

Most warm-water ocean currents move away from the equator and toward the poles because warm water is driven by ______ from ______ regions to _______ regions. A. convection; cold; hot B. conduction; cold; hot C. convection; hot; cold D. conduction; hot; cold

Answer 1

Answer:

Warm water is driven by convection from  hot regions to cold regions

Explanation:

At the equator, solar radiation on earth is at maximum, and the major percentage of solar radiation heats the surface of oceans and water bodies. The oceans and water bodies at the equator have a higher temperature when compared to the water bodies at the other parts of the world towards the poles.

Heat transfer by convection

Heat is transferred in fluid via convection, which is the movement of molecules of a fluid that is carrying thermal energy from a hotter region to a cooler region when there is a change in its temperature.

When oceans are heated at the equator the temperatures of the water bodies increases. Warm water is conveyed as vapor from the hot region to a cold region, to balance the temperature changes.

The ocean current moves via convection in the direction that is colder, to balance the temperature of the heated water bodies at the equator.

Answer 2

Answer:

Most warm-water ocean currents move away from the equator and toward the poles because warm water is driven by convection from hot regions to cold regions.
