Cold currents promote aridity of the land mass. Through the formation of coastal fogs, cold currents bring about reduction in temperature. Ocean currents modify the climate of an area by raising the temperature when cold and warm. The meeting of warm and cold currents promotes the formation of plankton, which serves as food for fish. …
Factors that Influence Ocean Currents are: Differences in temperature. Salinity The rotation of the earth. The prevailing planetary winds. The shape of the land masses.
1. Warm Ocean Currents: Movement of large masses of water from the warm equatorial region to the polar region with relatively high surface temperature. 2. Cold Ocean Currents: Movement from the cold polar region to the warm equatorial region.
This is the movement of large masses of surface water.
This is dependent on: The rate of evaporation. The degree of water mixing with ocean currents. The air temperature above the ocean The supply of fresh water from precipitation, streams and ice melt.
This is a line where all oceans that have the same degree of saltiness are joined together.
