Currents and Climate

The Ultimate Vocabulary for Currents and Climate

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.
