The oceans are primarily made of water. This water contains dissolved salts and other minerals, which give the oceans their characteristic salinity.
1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.2. A small part of chlorine is originated from the eruptions of submarine volcanoes.
The sea is salty because over billions of years, rain and rivers have washed mineral salts from rocks and soil into the ocean. These dissolved salts, such as sodium and chloride, accumulate in the ocean, making it salty.
No, most of the dissolved salts in the oceans come from natural processes such as weathering of rocks and volcanic activity. Human activities do contribute some salts to the oceans, primarily through industrial and agricultural runoff, but they are not the primary source.
Where a freshwater river drains into an ocean, the fresh water may mix with the salt water ... this is called brackish water.

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.
Salts are dissolved from the Earth and transported by rivers in seas/oceans.
Salts are dissolved from the Earth by rivers and transported in seas and oceans.
Salts are dissolved from the earth and transported by rivers in oceans.
Salt is dissolved from the earth and transported by rivers in seas and oceans.
Salts are dissolved from the Earth by rivers and transported in seas and oceans.
Salts are dissolved from the Earth and transported by rivers in seas and oceans.
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.
Salt is dissolved from the earth and transported to seas and oceans by the intermediate of rivers.
