The Earth is composed of over 70 percent water. It is estimated that there are over 50 quadrillion tons of salt in the worldâ??s oceans.

Salts are dissolved from the earth and transported in seas/oceans by rivers.
The salts are dissolved by rivers in the mountains and transported to Oceans and Seas.

About 86% of the dissolved salts in seawater are major salts, which include sodium chloride (table salt), magnesium chloride, and sulfate ions. These major salts make up the majority of the total dissolved solids present in seawater.
The dissolved salts in the Earth's oceans are primarily derived from the weathering and erosion of rocks on the Earth's surface. Water carries these dissolved ions into the oceans through rivers and streams, where they accumulate over time.
Salts are dissolved from the earth and transported in seas and oceans by rivers; a small part of salts is formed from submarine volcanoes eruptions.
