Question

Discuss the source of salt.

Answer 1

Sea water is a weak, but complex solution made up of many things including mineral salts and decayed biologic matter from marine organisms. Most of the ocean's salts are derived from gradual processes, such as weathering and erosion of the earth's crust and mountains by the dissolving action of rains and streams.

Answer 2

Explanation:

Salt in the ocean comes from land-based rocks. The rain falling on the surface includes some of the surrounding air's dissolved carbon dioxide. It results in a slightly acidic rainwater due to carbonic acid.

It is typically formed by salty water evaporation such as the marine water that contains the dissolved Na+ and Cl-ions. One finds rock salt deposits in arid regions of the world surrounding dry lake beds, marginal inland waters, and protected bays and estuaries.
