Only 3% of the water on Earth is freshwater. About 60% of that water is not available for man's use. Why is this?
salt concentrations.
in Earth's polar regions
glaciers and polar ice cap
at the bottom of Earth's oceans
Salinity
Sonar
it is frozen
evaporation and condensation
Tropical seas have a high rate of evaporation. Because of this, the water in tropical seas will have higher:
