Front

How are surface currents and deep water (density) currents connected?

Back

As surface currents move towards the poles, they cool, become more dense, and sink to become deep water (density) currents.

What causes the movement of deep water (density) currents?

Back

Differences in temperature and salinity.

Front

What is Continental Deflection in relation to ocean surface currents?

Back

It is the change in direction of a current as it approaches the coast of a continent.

Front

What role does the sun's energy play in ocean currents?

Back

The sun's energy heats the Earth's surface, influencing the movement of ocean currents.

Front

What is the difference between surface currents and deep water currents?

Back

Surface currents are driven by wind and the sun's energy, while deep water currents are driven by differences in temperature and salinity.
