Question

Quizplus · Accepted Answer

The key source of ions found in ocean water is the weathering of rocks on land, which releases ions into rivers and ultimately into the ocean. Rainwater may contain some ions, but it is a minor source compared to the weathering of rocks. The process of evaporation may concentrate ions in ocean water, but it does not create new ions. Marine organisms may contribute some ions to the ocean, but again it is a minor source compared to the weathering of rocks.
