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
Without any photosynthesis, there would be no plants which would lead to the many of the civilians of Earth starving to death. In the likely scenario where photosynthesis does not occur the world would most likely go into an apocalyptic way with the human race as well as many other mammals dying. The organisms that would survive might be used as a food source but the population would drastically decrease
