RAS question
The Gulf Stream is a warm ocean current flowing in:
Correct answer: (D) Atlantic Ocean.
The Gulf Stream is a warm ocean current of the Atlantic Ocean.
Explanation
The Gulf Stream is correctly placed in the Atlantic Ocean because it is described as a strong, warm current that carries warm water from the Gulf of Mexico into the Atlantic. From there, it runs along the eastern coast of the United States and Canada and continues across the North Atlantic towards Western Europe. That path explains why the current is usually taught under Atlantic circulation, not simply as a local Gulf current. Its warmth also matters climatically: by transporting warm water across the ocean, it helps keep Western Europe warmer than its latitude alone would suggest. The key identifying clues are therefore warm current, Gulf origin, US east-coast path, and Atlantic flow.
Why the other options are wrong
- (A) The Arctic Ocean is associated here with cold-current conditions, whereas the Gulf Stream is identified as a warm current moving through the Atlantic system.
- (B) The Pacific Ocean has the Kuroshio as its major warm current, so placing the Gulf Stream there confuses two different ocean-current systems.
- (C) The Indian Ocean is linked with the Agulhas Current, not with the Gulf Stream's Atlantic route.
Concept
This tests world geography's ocean-current mapping: candidates must match named warm currents with their ocean basins and broad paths. It recurs in RAS because ocean currents connect physical geography with climate effects, especially regional temperature patterns.
