What is the process called when salt is removed, especially from seawater?

  1. a. Corrosion

  2. b. Dehydration

  3. c. Desalination

  4. d. Deciduous

The correct answer is: c. Desalination

Desalination is the process of removing salt from seawater. It is not corrosion, which is the gradual degradation of a material due to chemical reactions. Dehydration is the process of removing water, not salt. Deciduous describes the shedding of leaves in plants, and is not related to the removal of salt from seawater.
