What process brings the deep cold ocean currents up to the surface?

• Conduction

• Global Wind Patterns

• Convection Currents

• Temperature and salinity

What happens to a current when it comes in contact with a continent or landmass?

• It continues over the continent

• It stops

• It changes direction

• It is absorbed by the land

A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.

• Gulf Stream

• Global Conveyor Belt

• Surface Current

• Gyre

If the Earth did not rotate on its axis, there would be no

• Greenhouse effect

• Coriolis effect

• Global warming

• Convection

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.

Why are ocean currents important to global climate?

• ocean currents circulate warm water from the poles to the equators

• ocean currents circulate warm water from equators to the poles

• ocean currents cause the prevailing winds

• ocean currents make water warmer at the equator
