<< previous question next question >>

Explanation:

• Option A: Convection is heat transfer by fluid movement, not related to ocean bulging at equator.
• Option B: Coriolis effect affects wind/current direction, not ocean bulging due to Earth's rotation's centrifugal aspect here.
• Option C: Earth's rotation creates centrifugal force, which is stronger at equator (greater distance from axis), causing ocean water to bulge there compared to poles.
• Option D: Thermohaline circulation is about density - driven ocean currents, not bulging.

Answer:

C. Centrifugal force
