Ocean and Air Currents

Differences in water temperature create movement in the Ocean because

• bodies of water at different temperature have different densities.

• warm water is pulled more by the force of gravity then cold water is.

• warm and cold water mix until they reach the same temperature.

• The ocean just likes to "move-it move-it".

What is the driving force of the deep water ocean conveyor belt?

• Winds push the deep water into the Pacific and Indian oceans.

• Gravity from the moon pulls the water towards the equator.

• The spinning of Earth makes the deep water current run in circular paths.

• Very cold temperatures at the poles create very cold, salty water that pushes the deep water current.
