Answer:
B) Convection
Step-by-step explanation:
One of the processes that causes the movement of ocean water is convection. Convection refers to the variation in water temperature that causes movement. This process occurs because when water becomes warmer, it becomes less dense. This causes it to move above cooler water, giving off heat. As it cools, the water moves down again. The repetition of this process results in the continual circulation of water on a global scale.
