Hint: The amount of dissolved inorganic salt of a water body is called its salinity. Solutes are the substances which are dissolved in the water.
Complete Step by Step Answer: The presence of dissolved salts in the water is called salinity. The average salinity of the ocean water is thirty five ppt. We can simply determine the salinity of the ocean water by evaporating one kg of its water and after this to weight the residue in grams. The average density of the ocean water is about 1.025 gm per ml at the surface of the ocean. Due to the added weight of salts, the water of the sea or ocean is more dense than the freshwater. Majority of salts that are dissolved in the ocean water are natrium and sodium. Many other major ions like magnesium, potassium, calcium and sulfate are also found in the ocean water. The most saline water found in the world is gaet’ale pond. This location is situated in the Danakil depression in afar, ethiopia. There are some of the most saline water bodies in the world namely the great salt lake, mono lake, salton sea, baltic sea, lake assal, the dead sea, garabogazkol aylagy, qarhan lake, salar de atacama.
So, the correct answer is option D.
Note: World’s highest salinity is recorded between fifteen degree and twenty degree latitudes. Whenever increasing the latitude then salinity gradually decreases. There are some of the most saline water bodies in india namely sambhar salt lake rajasthan, lonar crater lake maharashtra, chilka lake odisha, pulicat lake, pangong tso ladakh, pachpadra lake rajasthan.
