But we don't know whether this can account for the huge quantity of salt that is found in oceans. If all the oceans were dried up , enough salt would be left to build a wall 180 miles high and a mile thick. Or put in another way, the rock salt obtained if all the oceans were dried up would be about 15 times as large as the entire continent of Europe!
The common salt which we all use is produced from sea water or the water of salt lakes, from salt springs and from deposits of rock salt. The concentration of salt in sea water ranges from about three percent to three and one-half percent. Enclosed seas, such as the Mediterranean and Red Sea, contain more salt in the water than open seas. The Dead Sea which covers an area of about 340 square miles, contains about
11600000000 tons of salt!
On The average a gallon of sea water contains about a quarter of a pound of salt. The beds of rock salt that are formed in various parts of the world were alt originally formed by the evaporation of sea water millions of years ago. Since it is necessary for about nine-tenths of the volume of sea water to evaporate for rock salt to be formed, it is believed that the thick rock-salt beds that are found were deposited in what used to be partly enclosed seas. These evaporated faster than fresh water entered them, and the rock-salt deposits were thus formed.
Most commercial salt is obtained form rock salt. The usual method is to drill wells down to the sale beds. Pure water entered pumped down through a pipe. The water dissolves the salt and it is forced though an other pipe up to the surface.

C. more salt can be got for the same volume of water from some seas than from the ocean
D. the concentration of salt is greatest in rock-salt beds
52.Which of the following statements is NOT TOLD?
A. Both the Dead Sea and the Red Sea contain 3.5 per cent of salt in the water.
B. Rock Salt beds were a part of ancient seas.
C. To form rock salt, about nine tenths of the volume of sea water has to be evaporated.
