Which of the following is/are cold ocean current/currents?
1.Alaska Current
2.North Atlantic Drift
3.West Wind Drift
Select the answer using the code given below:

The correct answer is 3 only.

Key Points

• West Wind Drift is a cold ocean current that flows in the Southern Hemisphere and is also known as the Antarctic Circumpolar Current.
• The current is driven by the strong westerly winds, moving from west to east around Antarctica.
• It plays a crucial role in regulating the global climate by facilitating the exchange of heat and nutrients between the world's oceans.
• Alaska Current and North Atlantic Drift are warm currents, not cold currents, and flow in the Northern Hemisphere.

Additional Information

• Ocean Currents:
  • Ocean currents are continuous, directed movements of seawater generated by forces such as wind, the Coriolis effect, and temperature/salinity differences.
  • They are categorized into warm and cold currents depending on their temperature relative to the surrounding water.
• Warm Currents: These currents, such as the North Atlantic Drift and Alaska Current, originate near the equator and transport warm water to higher latitudes.
• Cold Currents: These currents, like the West Wind Drift and Labrador Current, transport cold water from polar areas to lower latitudes.
• Antarctic Circumpolar Current: This is the largest ocean current in the world, connecting the Atlantic, Pacific, and Indian Oceans and playing a key role in the global conveyor belt of ocean circulation.
• Impact of Ocean Currents: They influence global climate patterns, marine biodiversity, and even human activities such as fishing and shipping.
