Satellite view of La Plata River discharge to the Atlantic Ocean. One way minerals and salts are deposited into the oceans is from outflow from rivers, which drain the landscape, thus causing the oceans to be salty.seawater wasn't always so salty; when the Earth's oceans first formed about 3.8 billion years ago, as the surface of the planet cooled enough to allow water vapour to liquify, the oceans were mostly fresh water.
