WHY ARE THE OCEANS SALTY?
As water flows through rivers, it picks up small amounts of mineral salts
from the rocks and soil of the river beds. This very-slightly salty water
flows into the oceans and seas. The water in the oceans only leaves by
evaporating (and the freezing of polar ice), but the salt remains dissolved
in the ocean - it does not evaporate. So the remaining water gets saltier
and saltier as time passes.

Oceans cover about
70% of the Earth's surface. The oceans
contain roughly 97% of the Earth's water
supply.
