Question

Which statement describes why ocean currents are considered convection currents?

A) Warm water moves counterclockwise in the northern hemisphere

B) Warm water rises and cold water moves in to replace it

C) Convection currents move in closed paths around the ocean

D) Convection currents are affected by the directions of global winds

Answer 1

Answer: B) Warm water rises and cold water moves in to replace it.

Explanation: Ocean currents can be likened to convection currents because they involve the movement of water due to temperature differences. In the ocean, warm water tends to rise while cold water sinks. This movement creates a continuous circulation pattern, similar to how convection currents operate.

Answer 2

B) Warm water rises and cold water moves in to replace it.
