Consider the following ocean currents. 1. North Atlantic Drift 2. Oyashio current 3. Canaries current 4. California current 5. Alaska current Which of the above mentioned are cold currents ?

Option 2 : 2, 3 and 4 only

The correct answer is 2, 3 and 4 only.

• Ocean currents can be classified as cold and warm on the basis of temperature.
• Cold currents-
  • West Wind drift
  • Humboldt (Peru) current
  • California current
  • Canaries current
  • Oyashio current
  • Labrador current
  • Falkland current
• Warm currents-
  • Gulf Stream
  • North Atlantic Drift
  • Alaska current
  • Kuroshio current
  • Aghulas current
  • Brazilian current
  • North Equatorial current
  • South Equatorial current

• Ocean currents are streams of water flowing constantly on the ocean surface in definite directions.
• The ocean currents may be warm or cold.
• Generally, the warm currents originate near the equator and move towards the poles.
• The cold currents carry water from polar or higher latitudes to tropical or lower latitudes.
• The Ocean current influences the temperature conditions of the area.
• The areas where the warm and cold currents meet provide the best fishing grounds of the world.
• Seas around Japan and the eastern coast of North America are such examples.
