When a body of water or air moves in one direction, especially through another body of water or air which isn't moving as much. The ocean current is caused by a lot of different things, including the movement of the earth, the weather/wind, differences in temperature in different parts of the world, and the pull of the Sun and the Moon on the Earth.
