Answer:
The salt in the oceans comes from weathering and the erosion of the earth's crust.
Explanation:
The weathering can be described as the breaking down of rocks.
During the weathering of rocks, minerals will be dissolved from the land and salt is one of them. These minerals (salt included) will then be delivered into the oceans by erosion of the Earth's crust.
Erosion can be aided by wind, ice or water. Erosion removed weathered materials. When these weathered materials are removed, new materials (rocks) will be exposed to weathering thereby promoting continuous weathering processes
Solid water is less dense than liquid causing it to float while other substances are mainly more dense as solids.
