Which currents flow away from the equator?

• A. Cold currents
• B. Surface currents
• C. Warm currents
• D. Deep currents

Answer: (C)

Warm currents flow away from the equator because heat is transported from tropical regions toward the poles via the ocean’s surface layer. The equator heats surface water, making it lighter, and winds (the trade winds and westerlies) drive this water into large surface gyres that move water poleward. As a result, warm currents like the Gulf Stream and the Kuroshio carry heat away from the equator and toward higher latitudes, helping to warm regions farther from the equator. Deep currents and cold currents don’t follow this pattern: deep currents move due to density differences and can travel in different directions, while cold currents typically move toward the equator.
