Ocean Currents and Climate

What is one way that surface currents and deep currents connected?

• surface currents move to the equator, cool & sink, & become deep currents

• surface currents move above the deep currents but they don't connect

• surface currents move toward the poles, cool & become more dense and sink

• deep currents mix with colder, salty water & they rise to the top

Choose the statement that is true:

Choose one statement that describes the movement of ocean surface currents.

• Global winds push surface currents

• As water evaporates, the salt makes water less dense

• Cold water travels from the equator toward the poles

• Ocean surface currents don't move

Which of the following statements about the climate of places near the ocean is true?

• temperatures near the ocean are always warmer

• temperatures near the ocean are usually more extreme

• temperatures near the ocean are always cooler

• temperatures near the ocean can be milder if there is a cold ocean current

Choose a statement that describes the movement of ocean surface currents.

• Cold water rises in the ocean making the currents move

• The earth rotates causing the Coriolis Effect, which causes currents to curve

• fresh water in the ocean sinks sinks and causes currents to move

• warm water travels from the poles
