Oceans
| Question | Answer |
|---|---|
| Salinity | A measure of the amount of dissolved salts in a given amount of liquid |
| Thermocline | A layer in a body of water in which water temperature drops with increased depth faster than it does in other layers |
| Pack Ice | A floating layer of sea ice that completely covers an area of the ocean surface |
| Density | The ratio of the mass of a substance to the volume of a substance; commonly expressed as grams per cubic centimeter for solids and liquids and grams per liter for gases |
| Three main dissolved gasses found in ocean water? | Nitrogen (N), Oxygen (O), Carbon Dioxide (CO2) |
| Four ways gases can enter ocean waters. Most common one. | Streams, underwater volcanoes, marine organisms, and the most common one is the atmosphere |
| Relationship between water temperature and the amount of dissolved gases it contains | Colder water contains more dissolved gases |
| Relationship between temperature and density of ocean water | Colder water is more dense |
| Two factors that change the salinity of ocean water | Precipitation and evaporation |
| Surface current | A horizontal movement of ocean water that is caused by wind and that occurs at or near the oceans surface |
| Deep current | A stream like movement of ocean water for below the surface |
| Trade winds | Global winds between 0-30 degree latitude |
| Westerlies | Global winds between 30-60 degree latitude |
| Coriolis effect | The curving of the path of a moving object from an otherwise straight path due to Earths rotation |
| Gyre | A huge circle of moving ocean water found above and below the equator |
| Sargasso Sea | A vast area of calm, warm water in the middle of the North Atlantic Gyre. Named after Sargassum, a type of seaweed, that floats on the water |
| Antarctic Circumpolar Current | Worlds largest current, also called the west wind draft. Cold current; surface current |
| Equatorial Countercurrent | Weak, eastward flowing current that runs in the opposite direction of the equatorial currents. Warm current; surface current |
| Gulf Stream | Fast moving, warm surface current that flows up along the East coast of the U.S. |
| North Atlantic Current | Follows from the Gulf Stream. Warm surface current |
| Antarctic Bottom Water | Cold, deep current. Slow moving. Moves northward along the bottom of the ocean from Antarctica. |
