Why are the oceans salty
WHY ARE THE OCEANS SALTY?

  • Oceans cover about 70% of the Earth's surface.

  • The oceans contain roughly 97% of the Earth's water supply.

  • 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.
