Question

Explain the ocean as a drinking water resource?

Answer 1

Answer:

Oceans, which are the largest source of surface water, comprise approximately 97 percent of the Earth's surface water. However, since the oceans have high salinity, the water is not useful as drinking water. Efforts have been made to remove the salt from the water (desalination), but this is a very costly endeavor.

Answer 2

Answer:

Seawater is drawn from the ocean through intake pipes set out in the open ocean or below the seafloor. That water is filtered for bigger contaminants (and some essential tiny sea creatures) before it is sent through a reverse osmosis system that pressurizes the water through membranes, separating out the salt.
