Differences in the water's density.

Front

What role do ocean currents play in Earth's climate?

Back

They move heat around the planet.

Front

What happens when hot water is poured into a container with cold water?

Back

The less dense hot water forms a layer at the surface.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids.

Front

What is the significance of the Coriolis effect?

Back

It causes moving air and water to turn and twist rather than move in a straight line.
