Physical Characteristics of the Ocean

What is ocean water? A mixture of gases (air) and salt (NaCl) from rocks.

Ocean Water Marine organisms are dependent upon the air in the water to survive.

Ocean Water The amount of salinity in the ocean varies upon: Rates of evaporation and precipitation Amounts of erosion and runoff

Let’s Review What is ocean water made of? How can marine organisms survive in the ocean? If water evaporates in the ocean, what happens to the salinity? If large river empties into the ocean, what happens to the salinity?
