Why Are the Oceans Salty?

Why Are The Oceans Salty??

Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. … When rain falls, it weathers rocks, releasing mineral salts that separate into ions. These ions are carried with runoff water and ultimately reach the ocean.

Why are the oceans salty but not lakes?

In the beginning, the primeval seas were probably only slightly salty. But over time, as rain fell to the Earth and ran over the land, breaking up rocks and transporting their minerals to the ocean, the ocean has become saltier. Rain replenishes freshwater in rivers and streams, so they don’t taste salty.
