Question

Which of the following statements about desalination is true?

A) Desalination is an environmentally friendly process.
B) Desalination only involves the removal of impurities from water.
C) Desalination is a cost-effective method for obtaining freshwater.
D) Desalination involves the removal of salt from seawater.

Answer 1

Desalination is the process of removing salt from seawater to produce fresh water. It can be done through methods like evaporation, freezing, or using molecular membranes. Reverse osmosis is an effective method that forces water molecules through a semipermeable membrane, leaving the salt behind.

Step-by-step explanation:

Desalination is the process of removing salt from seawater to produce fresh water. It can be done through various methods, such as evaporation and condensation, freezing, or using molecular membranes. One effective method is reverse osmosis, which forces water molecules through a semipermeable membrane, leaving the dissolved salt behind. Large-scale desalination plants are common in desert areas like the Middle East and southern California, where they provide a significant amount of freshwater.
