Question

Which of the following processes is used for preparation of common salt from sea water?
(A) Distillation
(B) Evaporation
(C) Sedimentation
(D) Filtration

Answer 1

Hint :More over 70% of the Earth's surface is covered by seawater, which makes up the oceans and seas. Seawater is made up of 96.5 percent water, 2.5 percent salts, and trace quantities of dissolved inorganic and organic compounds, particles, and a few atmospheric gases.

Complete Step By Step Answer:
One of man's earliest chemical processes is the creation of salt. Although salt is naturally created as saltwater evaporates, the process may be simply replicated to achieve a larger output. Some salt is still made in the traditional way, although newer, quicker, and less expensive processes have been developed. The resulting result will have varying flavours and textures depending on the source of the salt and the process employed to make it.
There are three primary ways to get salt nowadays:
Seawater evaporation is a process that occurs when water evaporates.
Obtaining salt from the ground.
Brines made from salt.
Around 3.5 percent of the world's seas are made up of salt. When shallow ponds and bays dry up due to the sun and wind, huge salt crystals are left behind in the place where the salty water previously was. Seawater is deposited in enormous "concentrating ponds" to facilitate effective evaporation from the sun and wind while making sea salt on a huge scale. To provide ample time for evaporation, sea salt can only be produced in places with little rainfall. As a result, arid areas like the Mediterranean and Australia create a lot of sea salt.
Hence option B is correct.

Note :
Every day, ocean seawater is exposed to the sun. The water evaporates as a result of this. The water evaporates into the atmosphere, forms or dissolves in clouds, and then returns as precipitation. The water cycle is what it's called. When seawater evaporates from the ocean, the salt remains in the water.
