Etymology
Origin of freshwater
Explanation
The adjective freshwater describes an aquatic environment with very little salt, like a stream or a pond, or an animal that lives there. Water bodies that started as precipitation are freshwater, whether the water came from rain, snowfall, or melting glaciers. A freshwater lake, unlike a salt lake, sea, or ocean, has a low concentration of salts and other minerals. Freshwater bodies make up less than three percent of the earth's water. Freshwater fish and amphibians are the ones that are adapted to live in ponds, lakes, and streams, in contrast to those that thrive in salty water.
