Arrange the following seas in ascending order of concentration of salinity (minimum to maximum)

A. Red Sea

B. China Sea

C. Baltic Sea

D. Black Sea

Choose the correct answer from the options given below:  

The correct answer is C, D, B, A

Important PointsThe concentration of salinity in the world's seas and oceans is determined by several factors such as the amount of evaporation, freshwater input from rivers, precipitation, and sea ice formation.

Given the options and their known average salinities, the correct order from minimum to maximum salinity would be:

C. Baltic Sea:

• The Baltic Sea has a low salinity because it has a large amount of freshwater input from numerous rivers and relatively little evaporation due to its northern latitude and cooler climate.

D. Black Sea:

• The Black Sea also has lower salinity due to significant freshwater input from rivers such as the Danube, Dnieper, and Don.

B. China Sea:

• The China Sea, being part of the Pacific Ocean, has an average salinity similar to many other parts of the world's oceans.

A. Red Sea:

• The Red Sea has a high salinity due to high evaporation rates, low precipitation, and little freshwater input from rivers.

So, the correct answer is " C, D, B, A".
