Answer:
Water is transported from one area to another area that has little water.  
Water is collected and salt allowed to settle at the bottom. 
Explanation:
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.
