Question

How can rainfall affect the mineral content of ocean water?

Answer 1

An estuary is a place where seawater and freshwater mix.

Your tap water is treated water from which organisms and excess ions have been removed.

That rain-washed all sorts of particles and chemicals into the ocean.

After a few million years, it evened out and the amount of things coming into the ocean equaled the amount leaving.

It's a term called equilibrium.

Answer 2

Answer: The rainfall increases the mineral content of ocean water.

Step-by-step explanation:

The minerals in the oceanic water are added by the rainfall through surface runoff. It is a phenomena in which the large volume free flowing water flows over the surface of the soil. This water is not absorbed by the soil instead it takes away along with it all surface materials like chemical fertilizers, soil, sediments, inorganic and organic minerals and deposit them to the water body (ocean, river or others).

Thus this can be said that rainfall increases the mineral content of the ocean water.
