Ocean/Sea - Salinity (%)

Question

Which one of the following is not correctly matched ? 
Ocean/Sea - Salinity (%)

Accepted Answer

Option 4 is not correctly matched because the salinity of the Andaman Sea is generally lower than 40-42%. The typical salinity range for the Andaman Sea is closer to 30-34%, influenced by freshwater input from rivers like the Irrawaddy and the monsoon season. A salinity of 40-42% would be unusually high for this region.

Here's why the other options are more likely to be correctly matched (or at least closer to the typical ranges):

*   **Option 1 (Arctic - 20 to 35):** The Arctic Ocean's salinity varies greatly due to ice melt and river runoff. The given range of 20 to 35% is plausible, especially in areas with significant freshwater input.

*   **Option 2 (Bering - 28 to 33):** The Bering Sea's salinity generally falls within this range. It's influenced by both freshwater input and mixing with the Pacific Ocean.

*   **Option 3 (Okhotsk - 30 to 32):** The Sea of Okhotsk's salinity is also within this general range, influenced by factors like ice formation and river discharge.

Therefore, because the Andaman Sea's salinity is significantly lower than the stated 40-42%, Option 4 is the one that is not correctly matched.
