Explain the relationship between the general circulation of the air and the circulation of ocean currents
What will be an ideal response?
Answer: Both circulation patterns are a result of the unequal heating of Earth's surface. Because equatorial regions receive optimum radiant energy from the Sun, they have higher average temperatures than other regions. As air heated by the hot ground or ocean at the equator rises, it moves toward the polar regions, cooling gradually in the upper atmosphere. This cooled air then sinks at the poles and is drawn back to the warmer regions of the equator. The same is true for ocean water. Warm equatorial surface waters move toward polar waters where surface water cools and sinks to eventually flow back toward the equator.
