How does water inside of waves move?
Circular Motion
How does the Coriolis effect the movement of currents?
The Coriolis Effect is the curving of wind and water due to the rotation of the Earth. As the Earth spins, warm water travels to the poles, and cold water travels to the equator. Because water near the poles moves more slowly, it curves as it travels.
