Definition
Deeper currents caused by density that flow vertically.
What are Density Currents?
The changes in density.
What is the cause of Density Currents?
The circulation of thermal energy, nutrients, and gases.
What is the effect of Density Currents?
A large volume of water flowing in a certain direction.
What are Ocean Currents?
Currents driven by wind that flow horizontally and are shallower than other currents.
What are Surface Currents?
The major wind belts.
What is the cause of Surface Currents?
The movement of warm or cold water horizontally across the ocean’s surface.
What is the effect of Surface Currents?
A model of the large system of ocean currents that affects weather and climate by circulating thermal energy around Earth.
What is the Great Ocean Conveyer belt?
A narrow, powerful surface current that flows away from the shore.
What are Rip Currents?
The pressure building up from uneven buildup of water from waves.
What is the cause of Rip Currents?
The danger and responsibility for about 150 deaths every year in the United States.
What is the effect of Rip Currents?
The estimated time it takes for the Great Ocean Conveyer Belt to complete a cycle.
What is 1000 years?
The movement of wind and water to the right or left and clockwise or counterclockwise in different hemispheres.
What is the Coriolis Effect?
The Earth's rotation.
What is the cause of the Coriolis Effect?
The clockwise movement of liquids in the northern hemisphere and the counterclockwise movement of liquids in the southern hemispheres.
What is the effect of the Coriolis Effect?
The warm-water current that affects coastal areas of the southwestern United States
What is the Gulf Stream?
The vertical movement of water toward the ocean’s surface.
What is Upwelling?
Water displacement caused by wind blowing.
The movement of cold, nutrient-rich water from deep in the ocean to the ocean’s surface.
What is the effect of Upwelling?
The current that affects coastal areas of the southwestern United States.
