Q. Consider the following statements about the Sargasso Sea:
1.It is the only sea in the world that does not have a land boundary.
2.It records the lowest surface salinity in the Atlantic Ocean due to the constant influx of cold water currents.
Which of the statements given above is/are correct?
Answer: A
Notes:
Explanations:
- Statement 1 is correct: The Sargasso Sea is unique as it is the only sea on Earth that does not have a land boundary or a coastline. Instead, its boundaries are defined entirely by four circulating ocean currents that form the North Atlantic Gyre: the Gulf Stream (west), the North Atlantic Current (north), the Canary Current (east), and the North Atlantic Equatorial Current (south).
- Statement 2 is incorrect: The Sargasso Sea does not have the lowest salinity; in fact, it records some of the highest surface salinity levels in the Atlantic Ocean. This high salinity is driven by its location in a subtropical high-pressure zone, which features high rates of evaporation, minimal precipitation, and a lack of fresh water influx (since there are no rivers emptying into it).
