Expert Answer
Temperature, winds, gravitational pull of the sun, the earth and the moon, warm and cold currents are the factors that effects the movement of ocean water.
Temperature: Temperature affects the origin and nature of ocean currents. As equatorial and tropicalregions are warm, the oceans lying near the Equator and the tropics are warmer than the oceans lying near the Polar Regions.
Rotation of the Earth: The Earth rotates from west to east. The speed of rotation of the Earth ismaximum at the Equator. All the moving bodies move in a clockwise direction in the Northern Hemisphereand in an anti-clockwise in the Southern Hemisphere. This is also known as the Coriolis Effect.
Planetary Winds: Winds affect the movement of ocean water. The trade winds blow between the Equator and theTropics. These winds thus move the equatorial water towards the poles. For example, the SoutheastTrade Winds drift the equatorial current to the eastern coast of Australia as the warm East Australian Current.
The gravitational pull of the Moon and the Sun results in the movement of ocean waters n the form of tides.
