Which steps are involved in desalination of water? check all that apply.
a. salt is removed from ocean water to provide fresh water.
b. water is heated until it evaporates.
c. water is condensed and collected.
d. water is transported from one area to another area that has little water.
e. water is collected and salt allowed to settle at the bottom.

The correct answer is:

D. Water is transported from one area to another area that has little water.  

E. Water is collected and salt allowed to settle at the bottom.

Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.

Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.

All these steps are involved in desalination of water except for option A.

Explanation:

The desalination of water from first step to last step is mentioned as under:

D. Water is transported from one area to another area that has little water.

E. Water is collected and salt is allowed to settle at the bottom.

B. Water is heated until it evaporates.

C. Water is condensed and collected.

Option A is not a step which is involved in desalination, it is simply a definition of desalination of water because in desalination of water after a series of processes finally salt is removed from ocean water to provide fresh water.

the answer is c.
