- Ocean water is indeed a complex solution of
mineral salts and of decayed biologic matter
that results from the teeming life in the seas.
----. Other sources of salts include the solid
and gaseous materials that escaped from
the Earth's crust through volcanic vents.

The salt load of the streams entering the
ocean is just one of these factors

They still do not have a complete
understanding of its chemical composition

The ocean is not fresh like river water

Some of the ocean's salts have been
dissolved from rocks and sediments below
its floor

The oceans cover about 70 percent of the
Earth's surface
