Salt Water
| Term | Definition |
|---|---|
| Water Cycle | The continuous movement of water from Earth's surface to the atmosphere and back to the oceans |
| Evaporation | The Sun's heat changing liquid water changing to water vapor |
| Precipitation | Water (in any form) returning to Earth: Snow, rain, sleet, hail |
| Condensation | Cool temperatures changing water vapor to liquid water |
| Transpiration | Evaporation off of plants |
| Currents | Ocean water moving in a regular pattern determined by its temperature and density |
| Tides | The rise and fall of large bodies of water due to the moon's gravitational pull |
| Neap Tide | Occurs when the Sun, Earth, and moon are at an Ninety degree angle, very little tidal range |
| Spring Tide | Occurs when the Sun, Earth, and moon are in a straight line, creates a SUPER big tidal range |
| Waves | The wind's energy moving through ocean water |
| Gulf Stream | Warm ocean current which brings warm water from the Gulf of Mexico to the British Isles. It creates a mild climate for Britain. |
| Continental Shelf | Flat part of the continental margin |
| Continental Slope | The sloping part of the continental margin |
| Abyssal Plain | Large areas of flat land in the deep ocean |
| Mid-ocean ridges | Mountain chains which form at rift valleys |
| Seamounts | A volcanic mountain rising from the ocean floor that doesn't reach the surface |
| Trench | A long, deep valley or depression on the ocean floor through which old ocean floor sinks back toward the mantle. Ex: The Marianas in the Pacific |
| Volcanic Islands | Seamounts which rise above sea level |
| Crest | The top of a wave |
| Trough | The bottom of a wave |
| Cause of ocean tides | The gravitational pull of the moon |
| Coriolis Effect | The apparent "curving" of currents due to Earth's rotation |
| Deep ocean currents | Currents that occur below the surface; caused by high salinity and cool temperatures |
| Surface currents | Currents that occur at the surface; caused by global winds, continental deflection, and the Coriolis effect |
| Salinity | The amount of salt dissolved in water |
| Sink | Water that becomes more dense due to salinity and temperature changes will ____________ |
| Wave length | The horizontal distance between crests |
| Wave Frequency | the number of waves that pass a point in a certain amount of time. |
| Wave height | the vertical distance from the crest to the trough |
| Longshore drift | the movement of sand along a beach |
| Sandbar | As the waves slow down they deposit the sand they are carrying on the shallow, underwater slope, forming a long ridge |
| Barrier Beaches | Long sand deposits that form parallel to the shore and are separated from the mainland by a shallow lagoon. |
| Sand Dunes | Hills of wind blown sand |
| Groins | A wall of rocks or concrete that goes out into the beach to help prevent beach erosion |
