Question

Name one warm current and one cold current.

Answer 1

Hint: An ocean current is a continual and directed movement of sea water generated by a number of forces. The forces acting are the Coriolis effect, temperature and salinity differences.

Complete Answer:
-Warm ocean currents stream away from the equatorial region on the western side of ocean basins.
- It carries warm water to Iceland and the British Isles. As a result, these places have warmer climates than they would otherwise.
-A region of warm water and light winds, the Sargasso Sea has fairly calm seas.
- Examples of warm currents; The Gulf Stream current in the North Atlantic and the Kuroshio Current current in the North Pacific.

-Cold currents are the ones which flow towards the equator.
-Cold currents can also stream out of far northern regions creating a hazard for ships in the North Atlantic.
- The Labrador Current meets the Gulf Stream off the coast of Newfoundland.
-Two other crucial cold currents originate in northern areas, the East Greenland Current flows into the North Atlantic through the Strait of Denmark and the Oyashio Current flows through the Bering Strait.

Note: The three important ocean currents are; The North Equatorial Current, the Gulf Stream, the North Atlantic Current, and the Canary Current.Ocean currents are mainly horizontal water movements.
