Currents and Water Cycle Review

Currents are caused by

• gravitational pull of the moon

• gravitational pull of the sun

• winds, the earth's rotation and differences in water density

• the earth's rotation

What does a surface current do when it meets a continent?

• The ocean current changes direction by deflecting.

• The ocean current continues on land.

How do ocean current temperatures affect the nearby city temperatures?

• Warm ocean currents from the poles bring warmer temperatures and cold ocean currents from the equator bring colder temperatures to those cities.

• Cold ocean currents from the poles bring cooler temperatures and warm ocean currents from the equator bring warmer temperatures to those cities.

How do warm-water currents affect the coastal areas where they flow?

• They create greater rainfall along the coast.

• They create unusually cool climates for the latitude.

• They make coastal climate cooler than the inland climate.

• They create unusually warm climates for the latitude.

What happens to ocean water that is very salty?

• It evaporates quickly.

• It sinks because it is more dense.

• It rises because it is less dense.
