All of the elements like sodium, chloride, magnesium, sulfate, silica, calcium and potassium got into the oceans this way. This process is still going on today but at a much slower rate. We got a good look at it this winter with all of the erosion that occurred in our area. Another way elements get into the seawater is through underwater volcanoes.
