MPPSC 2021 Prelims Paper-I · Question 11 of 100

Correct — A, North Atlantic Ocean. The Sargasso Sea lies in the middle of the North Atlantic, roughly between the West Indies and the Azores. It is the only 'sea' in the world with no land boundary at all — instead it is enclosed on every side by ocean currents: the Gulf Stream to the west, the North Atlantic Current to the north, the Canary Current to the east, and the North Atlantic Equatorial Current to the south. These four currents together form the North Atlantic Subtropical Gyre, and the calm, slow-circulating water trapped inside it is the Sargasso Sea.

• (b)South Atlantic Ocean — Wrong hemisphere — the South Atlantic has its own gyre (bounded by the Brazil, Benguela and South Equatorial currents), but the Sargasso Sea itself is a North Atlantic feature.
• (c)Indian Ocean — The Indian Ocean has no equivalent named 'Sargasso'-type gyre-sea; this option confuses ocean basins.
• (d)North Pacific Ocean — The North Pacific has its own subtropical gyre (associated with the 'Great Pacific Garbage Patch'), but that is a distinct feature — the Sargasso Sea specifically names the North Atlantic gyre's still water.

The Sargasso Sea is defined not by land coastlines but purely by ocean currents — it is the calm, current-bounded interior of the North Atlantic Subtropical Gyre. It takes its name from the free-floating brown seaweed genus Sargassum that mats its surface, historically unsettling to sailors because of the weed and the lack of wind (part of what fed the 'Bermuda Triangle' region's mystique, since the Sargasso Sea's western edge lies near Bermuda).

Exam-setters like this fact because it breaks the usual pattern of 'seas are bounded by land' — students who assume every named sea touches a coastline get pulled toward the wrong ocean or a plausible-sounding distractor.

• Only sea in the world with no land boundary — defined entirely by four ocean currents
• Boundaries: Gulf Stream (west), North Atlantic Current (north), Canary Current (east), North Atlantic Equatorial Current (south)
• Named after the free-floating seaweed genus Sargassum that covers its surface
• Known spawning/breeding ground of the European eel and American eel

• Assuming every 'sea' must be bounded by land, like the Mediterranean or Arabian Sea
• Confusing the Sargasso Sea with the Bermuda Triangle — they overlap geographically but are not the same concept

MPPSC/UPSC typically ask a direct 'where is X sea/current located' locate-the-feature question, or test the unique current-bounded (not land-bounded) nature of the Sargasso Sea.

No directly related past PYQ was found.

  The Sargasso Sea is unique among the world's seas because it:

  • (a)is entirely landlocked
  • (b)has no land boundary and is enclosed only by ocean currents
  • (c)is the smallest sea in the world
  • (d)lies in the Southern Hemisphere

  Answer(b) It has no land boundary and is enclosed only by ocean currents.

  Which ocean current forms the western boundary of the Sargasso Sea?

  • (a)Gulf Stream
  • (b)Canary Current
  • (c)Benguela Current
  • (d)Humboldt Current

  Answer(a) Gulf Stream.
