Gulf Stream is a warm ocean current because it ________.

  • A.moves from poles to equator
  • B.gets heated from underground
  • C.gets heated by hot springs
  • D.originates near the equator

Answer: D

The Gulf Stream is warm because it originates near the equator.

Ocean currents take on the temperature of the region they start from. Currents that originate near the equator, where the water is heated by the sun, are warm and carry that warmth towards the poles; the Gulf Stream flows from the Gulf of Mexico across the Atlantic towards north-western Europe.

Currents moving from the poles towards the equator are cold currents, the opposite case. Ocean currents are not heated from underground or by hot springs.
