Consider the following statements about the Sargasso Sea : 1. It is the only sea without a land boundary. 2. The Sargasso Sea records the lowest salinity in the Atlantic Ocean. Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.Both 1 and 2
- D.Neither 1 nor 2
Correct answer
Explanation
The correct answer is A, 1 only. The Sargasso Sea lies in the North Atlantic Ocean, east of Bermuda, and it is the only sea in the world with no land coast. Its boundaries are formed by four ocean currents that make up the North Atlantic Gyre: the Gulf Stream on the west, the North Atlantic Current on the north, the Canary Current on the east and the North Equatorial Current on the south. So statement 1 is correct. Statement 2 is wrong because the Sargasso Sea has one of the highest salinities in the open Atlantic, about 36 to 37 parts per thousand. Its waters are calm and warm, evaporation is high, rainfall is low and no river brings fresh water into it. The sea is named after the floating brown seaweed Sargassum, and it is the breeding ground of European and American eels. Option B is wrong because statement 2 is false. Option C is wrong for the same reason. Option D is wrong because statement 1 is true. Exam tip: Sargasso Sea, no land boundary, bounded by currents, high salinity, floating Sargassum weed.
