Detailed explanation-1: -Seawater has unique properties: it is saline, its freezing point is slightly lower than fresh water, its density is slightly higher, its electrical conductivity is much higher, and it is slightly basic.
Detailed explanation-2: -Water from oceans can be used for making hydroelectricity, a form of renewable source of energy. It can be used as a cheap transport method. They can be used for activities like scuba diving, water sports, etc. which is a means of boosting the tourism and economic growth of a country.
Detailed explanation-3: -Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases. Seawater constitutes a rich source of various commercially important chemical elements.
Detailed explanation-4: -The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface. The planet has one global ocean, though oceanographers and the countries of the world have traditionally divided it into four distinct regions: the Pacific, Atlantic, Indian, and Arctic oceans.
