The westward deflection of equatorial winds. The movement of rising air currents away from the equator. The rotation of storm systems. The formation of calm "eyes" in the centers of cyclones.
I gave my students this multiple choice question: The Earth's equator receives more direct sunlight than the regions to its north and south. This distribution of sunlight accounts directly for which phenomenon?

Only one answer is correct among these 4 choices:
- The westward deflection of equatorial winds.
- The movement of rising air currents away from the equator.
- The rotation of storm systems.
- The formation of calm "eyes" in the centers of cyclones.

Could you tell me which one is correct?

The movement of rising air currents away from the equator.
