Where does the lower salinity water rest with the higher salinity dense water?

Correct option is A

The correct answer is (A) Above.

• In a body of water, lower salinity water is less dense and therefore rests above the higher salinity water, which is denser and sinks to the bottom.
• This stratification is a common phenomenon in oceans and seas, where differences in salinity, along with temperature, create layers in the water column.

Salinity and Density:

• Salinity refers to the concentration of dissolved salts in water. Higher salinity increases the density of water.
• Water bodies often have layers based on salinity and temperature, with less dense, lower salinity water resting above denser, higher salinity water.
• This stratification can affect marine life, ocean currents, and the mixing of nutrients in the ocean.
• Thermocline and halocline are terms used to describe the layers formed due to temperature and salinity differences, respectively.
