Can you explain how salt from the sea is returned to the land

The salinity of ocean is either due to eruption of volcano or released through the earth crust.

Further Explanation:

Salt is the basic component of the sea water other than organic and inorganic constituent present in the sea water. The salt present in the ocean remains relatively constant for over a century therefore, the addition and removal of salt remains in relative equilibrium.

The rock and the earth crust helps in adding the salt to the ocean water. It is postulated that salt present in the ocean is excreted from the bottom crust of the ocean. There is a other theory which postulate that the salt present in the ocean is due to volcanic eruption. The hydrogen sulfide and chlorine is released in the atmosphere during volcano eruption which enters into the ocean through rain water.
