| lowest part of a wave | trough |
| highest part of a wave | crest |
| why waves increase in height as they approach shore | waves interact with ocean floor |
| waves get their energy from... | the wind |
| ocean current | large stream of moving water that flows through oceans |
| upwelling | rising of cold, deep ocean water to replace warm water at the surface |
| cause of Global Conveyor Belt | changes in density |
| Most dense seawater | Cold & Salty |
| Energy moves through waves in | a straight line |
| Coriolis Effect | The curving of an object from a straight path due to the Earth's rotation |
| Where does surface water sink and begin the Global Conveyor Belt? | the poles |
| Ocean currents in the northern hemisphere | turn clockwise |
| Ocean currents in the southern hemisphere | turn counterclockwise |
| A rotating current system within an ocean basin | gyre |
| bring warm water away from the equator | Warm water currents |
| bring cold water away from the poles | Cold water currents |
| Surface Currents are controlled by | wind, the Coriolis effect, and continental deflections |
| Wave height | distance from top to bottom of a wave |
| Wavelength | distance from one wave to another |
| water particles in a wave move in | up and down in circular motions |
