Ocean Currents and Climate

How are surface currents and deep currents connected? Pick TWO.

• 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 warmer, less salty water & they rise to the top

Choose 3 correct statments about the water at location #1.

• the water at location #1 is less dense because it's warmer

• the water at location #1 is the most dense because it has higher salinity

• the water at location #1 is the most dense because it is cooler

• the water at location #1 is less dense because it has less salt than location #3

• the water at location #1 is less dense than the water at location #3
