Are currents that occur in deep water, warm?

The answer is no, the water at the bottom is cold and the water at the top is cold

Believe it or not the answer is no. The currents are actually cold due to the movement of water mostly. Currents have more movement in them so the water travels from place to place faster without having to use energy. If water movement used enough energy in currents then it would produce heat making the current warm. In this case no, the currents don’t use enough energy to make heat.

The answer is a since the earth has different layers
