| Question | Answer |
|---|---|
| The surface currents in each ocean form ______? | gyre |
| A ____________ can affect weather and climate? | ocean current |
| Some currents move along the water's surface and others are examples of _________? | upwelling |
| Because of the ______________ ocean currents flow counterclockwise in the southern hemisphere and clockwise in the northern hemisphere | Coriolis effect |
| A ______ is a large volume of water flowing in a certain direction. | ocean current |
| surface currents are caused by _____ from the wind. | friction |
| Surface currents move water _____ and extend to about 400 m below the surface | horizontally |
| A _____ is a circular system of currents | gyre |
| The _____ is the movement of water to the right or left and is caused by Earth's rotation | Coriolis effect |
| the vertical movement of water toward the ocean's surface is an _____ ? | upwelling |
| The vertical movement of water from the surface to deeper parts of the ocean is a ______ current | density |
| Density currents are caused by density changes which are brought on by changes in temperature or _____ | salinity |
| The oceans are a major part of the ______ | water cycle |
| The Great Ocean Conveyor Belt is a model used to explain how ocean currents circulate ______ around Earth | thermal energy |
| Ocean currents affect weather and ____ | climate |
| An ocean current is a large volume of water flowing in a certain direction | True |
| Friction generated by wind on water can move the water to form surface currents | False- |
| Surface currents move water vertically and less than 400 m below the surface | False-horizontally |
| In each ocean the major surface currents form circular systems of currents called density currents | False-gyre |
| Earth's rotation causes the Coriolis effect which influences the direction that ocean currents flow | True |
| Density currents move water vertically toward teh ocean's surface | False-upwelling |
| The oceans are hte major source of moisture for the water cycle | True |
| Ocean currents affect weather and climate by redistributing wind energy | True |
| Density currents are caused by density changes which are brought on by changes in temp or wind | False salinity |
