Why are ocean currents considered convection currents?

• Warm water moves counterclockwise in the northern hemisphere.

• Warm water rises and cold water moves in to replace it.

• Convection currents move in closed paths around the oceans.

• Convection currents are affected by the directions of global winds.

• land is a better insulator.

• water is a better conductor

• water is a better insulator.

• land has a higher heat capacity.
