Explain how salinity and temperature affect water density and how the salinity of the oceans can be both increased and decreased
finlep [7]

Answer:

Salinity is the <em><u>salt concentration</u></em> in water. Oceans salinity and temperature affect density of water, Higher the salinity denser the water and Lower the temperature denser the water.

Explanation:

As we go down in the ocean , temperature goes down and denser the water.

Less dense water will be on top and higher the density will be on bottom. Warmer water will be on top.

Salinity <em> increased</em> in ocean on evaporation of sea water and formation of ice in water. Weathering of rocks , formation of soil also add minerals and salt in ocean.

Melting of snow, ice in sea, addition of river freshwater and precipitation of rain <em>decrease </em>the salinity of ocean.
