Read each question carefully and answer to the best of your ability. Some questions may require you to refer to a diagram.
1. What is the primary force that drives surface ocean currents?
Earth's rotation
Winds
Moon's gravity
Volcanic activity
2. Deep ocean currents are mainly driven by differences in:
Wind speed
Salinity and temperature
Ocean depth
Sunlight
3. The continuous movement of ocean water is called an ocean .
4. Warm ocean currents typically flow from the towards the poles.
5. The Coriolis Effect is caused by the of the Earth.
6. Explain how ocean currents influence global climate patterns.

True
False
8. Upwelling brings cold, nutrient-rich water to the ocean surface.
True
False
Match the term on the left with its description on the right.
9. Surface Currents
a. Driven by wind and Earth's rotation
10. Deep Currents
b. Driven by differences in temperature and salinity
11. Gyre
c. Large system of circulating ocean currents
12. Observe the diagram below showing convection currents. How does this model relate to the formation of deep ocean currents?
