RAS question
The Gulf Stream, a warm ocean current, flows in:
Correct answer: (C) North Atlantic Ocean from Gulf of Mexico towards northwest Europe.
The Gulf Stream is a warm, powerful western boundary current of the North Atlantic that originates in the Gulf of Mexico and flows towards north-western Europe.
Explanation
The Gulf Stream fits option C because it is not just any warm current; it is a powerful western boundary current in the North Atlantic. It originates in the Gulf of Mexico, then moves along the eastern coast of the United States and continues across the Atlantic towards Europe, where it is associated with the North Atlantic Drift. It is large in scale, about 100 km wide and moving near 2 m/s, and NOAA confirms that Gulf Stream waters travel rapidly and extend towards Europe. This eastward extension matters climatically: the current helps keep western European countries, including Britain and Norway, warmer than places at similar latitudes such as Labrador in Canada.
Why the other options are wrong
- (A) The Indian Ocean along the African coast is a different ocean-current setting, whereas the Gulf Stream is a North Atlantic current after originating in the Gulf of Mexico.
- (B) The South Pacific Ocean cannot be correct because the Gulf Stream is a North Atlantic current, not a Pacific current.
- (D) The Arctic Ocean is outside the stated route: the Gulf Stream runs from the Gulf of Mexico through the North Atlantic towards Europe, not as an Arctic Ocean current.
Concept
This tests the physical geography concept of major ocean currents and their climatic influence. RAS repeatedly asks such map-based current questions because currents connect ocean circulation, regional climate and world-location awareness in one fact pattern.
