2. The North Atlantic Drift
3. The Labrador Current
4. The Oyashio Current
Select the correct answer using the codes given below:

[A] 1, 2 and 3 only

[B] 2 and 4 only

[C] 3 and 4 only

[D] 1 and 4 only

Answer: C
Notes:

Cold currents flow toward the equator on the eastern side of ocean basins. Examples of cold ocean currents include the Canary Current in the North Atlantic, the California Current in the North Pacific, and the Benguela Current in the South Atlantic.  

  • Cold currents can also flow out of far northern regions. The Labrador Current flows out of Baffin Bay and past Labrador, the coastal part of the Canadian province of Newfoundland.  
  • The current carries icebergs from Baffin Bay, creating a hazard for ships in the North Atlantic. The Labrador Current meets the Gulf Stream off the coast of Newfoundland.  
  • When warm, moist air from the Gulf Stream blows over the cold Labrador Current, water vapor condenses. This results in some of the thickest fogs in the world.  
  • Two other important cold currents originate in northern regions. The East Greenland Current flows into the North Atlantic through the Strait of Denmark.  
  • The Oyashio Current flows through the Bering Strait between Siberia and Alaska and into the North Pacific.
