Warm surface currents transport heat toward higher latitudes. Which option best completes this statement?

• A. Toward lower latitudes
• B. Toward equator
• C. Toward polar regions
• D. Toward higher latitudes

Answer: (D)

Warm surface currents act as heat conveyors, moving energy from the warm tropics toward cooler regions at higher latitudes. This poleward transport warms mid-latitude and polar areas and helps moderate climates along coasts fed by these currents. Saying the heat moves toward higher latitudes directly describes this northward (poleward) energy flow, which fits the real pattern of oceanic heat redistribution. Moving heat toward lower latitudes or toward the equator would not reflect how these currents spread warmth across the globe. In short, the best completion captures the idea of heat being carried toward the cooler, higher-latitude regions.
