How is seawater different than fresh water?
user
Seawater contains much more salt than fresh water, which means it is heavier. The pressure from the density of the water can be as much as 4,000 pounds per square inch. Water also evaporates quickly in the warm temperatures near the equator, which then rains and replenishes the oceans with fresh water. This creates cycles of evaporation and precipitation.
