What is responsible for the saltiness of ocean water?

1 Answer

Answer:

Salts

Explanation:

As the rain falls on the rocky ground, it brings about erosion due to some dissolved #CO_2# contained, which reacts as it is acidic.

This creates ions which are carried towards the ocean through the rivers which accumulate more salts as the water descends transporting its minerals.

Nearly 90% of dissolved ions or salts in the ocean are sodium and chloride ions in the ocean. (like the common salt #NaCl#)
