Question

The oceans cover about 70 percent of the Earth's surface. Ocean water contains salts and we say that ocean water has a certain salinity. You are very familiar with a salt: NaCl. But there are other salts in the oceans. Scientists estimate that if the salt in the oceans could be removed and spread evenly over the Earth's land surface it would form a layer more than 500 feet thick, about the height of a 40-story office building (NOAA). Scientists also believe that the amount of salt in the Earth's oceans remains pretty constant. Salt water - fresh water. Where did the salt in the oceans come form? Salts dissolve in water. Look at the image of the water cycle. Hypothesize as to the original source of the salts in the oceans on Earth. A) Water collecting on Earth chemically erodes the continental crust. B) Elements found within the Earth, dissolve in water, enter the water cycle, and return to the oceans. C) Elements in the atmosphere fall back to Earth when combined with water in some form of precipitation. D) Evaporation leaves behind salts that eventually combine with the water that covers the oceanic plates.

Explanation

The salt in the oceans comes from weathering and the erosion of the earth's crust.

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 the 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
