| Question | Answer |
| Surface currents in each ocean form _______________. | circular systems of currents: gyres |
| A ___________________ can affect weather and climate. | large volume of water flowing in a certain direction: ocean current |
| Some currents move along the water's surface, and others are examples of ____________________________________. | vertical movements of water toward the ocean's surface: upwelling |
| Because of the ________________________ ocean currents flow counterclockwise in the southern hemisphere and clockwise in the northern hemisphere | movement of water to the right or left that is cause by Earths rotation: Coriolis Effect |
| An _________ 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 current. | 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 part's 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 |
| 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. | true |
| 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/gyres |
| Earth's ROTATION causes the Coriolis effect, which influences the direction that currents flow. | true |
| DENSITY CURRENTS move water vertically toward the ocean's surface. | false/upwellings |
| AN UPWELLING moves water vertically from the surface to deeper parts of the ocean. | false/a density current |
| Density currents are caused by density changes, which are brought on by changes in temperature or WIND. | false/salinity |
| The oceans are the major source of moisture for THE WATER CYCLE. | true |
| The Great Ocean Conveyor Belt is a model used to explain how ocean currents circulate THERMAL ENERGY around Earth. | true |
| Ocean currents affect weather and climate by redistributing WIND energy. | false/water |
| What forms gyres in each ocean? | currents moving in a circular direction |
| What affects the size of a gyre? | the wind/topography |
| How are gyres in the northern hemisphere and the southern hemisphere different? | gyres in the northern hemisphere are clockwise, and gyres in the southern hemisphere are counterclockwise. |
| Factors that affect the flow of surface currents. | gyres, the Coriolis effect, topography, wind speed/direction. |
| An upwelling is caused as the surface water moves away from shore and deeper water below rises to replace it. | true |
| Salty water sinks below water that is less salty | true |
| Density currents circulate nutrient and gas rich water through the ocean. | true |
| What two things do ocean currents transfer that affect weather? | thermal energy and moisture |
