Currents and Climate
The Ultimate Vocabulary for Currents and Climate
Question | Answer |
---|---|
Currents | A large stream of moving water that flows through the oceans.Carries water great distances. |
Surface Currents | Are horizontal, stream-like movements of water that are found at or near the surface of the ocean. |
Deep Currents | Movements of water far below the surface, which differs in density. |
Continental Deflection | When surface currents meet the continents the currents deflect/or change direction. |
Density | Is the amount of matter in a given space or volume. D=M/V |
Sallinity | Is a measure of the amount of salts or solids dissolved in a certain amount of liquid. |
Coriolis Effect | The curving of the path of a moving object from an otherwise straight path due to the Earth's rotation. This cause the winds to go clockwise in the northern hemisphere. |
Gulf Stream | Is one of the largest surface currents in the world. |
Upwelling | Happens when cold, nutrient-rich water from the deep ocean replaces warm surface water. |
Plankton | Are organisms that float or drift near the ocean's surface. |
El Nino | A change in the surface water temperature in the pacific ocean that produces a warm current. |
La Nina | A change in the eastern pacific ocean in which the surface water temperature becomes unusually cool. |
Rotation | Spinning of an object on an axis. Earth:24hrs |
Climate | Average of weather over a long period of time. |
Direction of the Currents | Northern Hemisphere:Clockwise Southern Hemisphere:Counterclockwise |
