Greenfield-Oceans
Oceanography and Hydrology
| Term | Definition |
|---|---|
| The continuous movement of water from Earth's surface to the atmosphere and back to the oceans | Water Cycle |
| Pollution coming from many different sources such fertilizer and pesticides from farmingwhich runs off into rivers and streams When water becomes more dense, then it will __ | Non-point source pollution |
| Pollution which comes from a specific site EXAMPLE- oil spills | Point source pollution |
| The Sun's heat changing liquid water to water vapor | Evaporation |
| Water (in any form) returning to Earth | Precipitation |
| Cool temperatures changing water vapor to liquid water | Condensation |
| Evaporation off of plants | Transpiration |
| Ocean water moving in a regular pattern determined by its temperature and density | Currents |
| The rise and fall of large bodies of water due to the moon's gravitational pull | Tides |
| Occurs when the Sun, Earth, and moon are at an Ninety degree angle, very little tidal range | Neap Tide |
| Occurs when the Sun, Earth, and moon are in a straight line, creates a SUPER big tidal range | Spring Tide |
| The wind's energy moving through ocean water | Waves |
| Warm ocean current which brings warm water from the Gulf of Mexico to the British Isles. It creates a mild climate for Britain. | Gulf Stream |
| Flat part of the continental margin | Continental Shelf |
| The sloping part of the continental margin | Continental Slope |
| Large areas of flat land in the deep ocean | Abyssal Plain |
| Mountain chains which form at rift valleys | Mid-ocean ridges |
| A volcanic mountain rising from the ocean floor that doesn't reach the surface | Seamounts |
| 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 | Trench |
| Seamounts which rise above sea level | Volcanic Islands |
| The top of a wave | Crest |
| The bottom of a wave | Trough |
| The gravitational pull of the moon | Cause of ocean tides |
| The apparent "curving" of currents due to Earth's rotation | Coriolis Effect |
| Currents that occur below the surface; caused by high salinity and cool temperatures | Deep ocean currents |
| Currents that occur at the surface; caused by global winds, continental deflection, and the Coriolis effect | Surface currents |
| The amount of salt in water | Salinity |
| Water that becomes more dense due to salinity and temperature changes will ____________ | Sink |
