Currents Review

Use your notes and read the text below to help you answer the questions. Summary Which of the following is caused by differences in ocean water density? Surface Currents Deep Currents Waves Coriolis Effect In the northern hemisphere, the Coriolis effect causes currents to do which of the following? Curve Counterclockwise Curve Clockwise Reverse Direction Sink Fill in the Blank 1. Surface currents are caused by wind.2. When a surface current moves toward the poles, its water temperature decreases and its salinity increases. The water becomes denser and sinks. Then, the cold water flows back along the ocean floor with a deep current.3. Deep currents move and mix water around the world. They carry cold water from the poles toward the equator.4. Currents are large streams of moving water that flow through the oceans.5. The effect of Earth's rotation on the direction of winds and currents is called the Coriolis Effect.6. Climate is the pattern of temperature and precipitation typical of an area over a long period of time.
