Correct Answer - Option 1 : Gulf stream

The Gulf stream is a Warm Ocean current flowing along the eastern coast of North America. 

Ocean current:

  • Ocean currents and planetary winds affect world climate on a larger scale.
  • An ocean current is a continuous, directed movement of seawater.
  • It is generated by a number of forces acting upon the water, including wind, the Coriolis effect etc.

Gulf stream:

  • The Gulf Stream is a strong ocean current that brings warm water from the Gulf of Mexico into the Atlantic Ocean.
  • It extends all the way up the eastern coast of the United States and Canada and on to western Europe.
  • This strong current of warm water influences the climate of the east coast of Florida.
  • It keeps temperatures there warmer in the winter and cooler in the summer than the other southeastern states.
  • Since the Gulf Stream also extends toward Europe, it warms western European countries as well.
  • In fact, England is about the same distance from the equator as the cold regions of Canada, yet England enjoys a much warmer climate.
  • If it weren’t for the warm water of the Gulf Stream, England would have a much colder climate.
  • The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
  • The Gulf Stream is part of the North Atlantic Subtropical Gyre.
  • It is a deep ocean current.

Thus, the correct statement with respect to Gulf Stream is that it is a warm ocean current that influences weather along the east coast of the United States.

Ocean current Characteristics
Canary current
  • It is a cold current in North Atlantic Ocean
  • This Eastern Boundary Current is a part of the North Atlantic Gyre.
  • It is named after the Canary Islands.
  • Presence of Upwelling.
Kuroshio current
  • This west boundary current is also known as Japan Currant or Black Current.
  • The term “Kuroshio” in Japanese means “Black Stream ''.
  • It is found in the Pacific Ocean analog of the Gulf Stream in the Atlantic Ocean.
  • The average surface temperature of this current is warmer than the surrounding ocean. This also helps in regulating the temperature of Japan, which is relatively warmer.
Brazilian current
  • It is a warm water current in the south Atlantic Ocean
  • It flows south along the Brazilian south coast to the mouth of the Rio de la Plata.
