What role does heat energy from the sun play in influencing ocean currents?
a) the higher rate of evaporation at the equator causes water from the poles to move toward the equator.
b) the polar ice caps melt due to the heat of the sun, causing warm currents to move toward the equator.
c) the colder temperatures at the poles causes water to freeze and expand, pushing cold currents toward the equator.
d) the warm water at the equator moves toward the poles and the cooler water from the poles moves toward the equator.

The correct answer is - D) The warm water at the Equator moves toward the poles and the cooler water from the poles moves toward the Equator.

The Sun is the factor that is the most determining of how the ocean currents will move across the globe. The reason for that is that the Sun is the one that heats up the waters. The waters at the lower latitudes get much more heat, thus they become warm, while the waters close to the poles are cold because they receive much less heat because the Sun rays fall at a much lower angle, thus they are more dispersed.

The warm water and the cold water have different densities, and that causes them to move. The warm water is less dense, so it moves on the surface and goes from the lower latitudes to the higher latitudes, while the colder warm is denser, so it moves from the higher latitudes toward the lower latitudes as a deep ocean current.

explanation:

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
