Question

Define freshwater.

Answer 1

Hint: Freshwater body is mineral-rich water like chalybeate spring. Some other examples of freshwater are ponds, lakes, glaciers, icebergs, rivers. Underground water is also referred to as a source of freshwater.

Complete step by step answer:
Freshwater is defined as naturally occurring water which contains less concentration of dissolved salt and other impurities. It contains less than 500 ppm of dissolved salt.
Due to the presence of a minimal quantity of dissolved salt, the freshwater is not considered as seawater or brackish water, as in seawater maximum amount of dissolved salt is present. Sat is extracted from seawater by the process of sublimation.
Water is the need for humans as well as other living organisms. All the living species depend on water for their survival.
Freshwater cannot be used always for the drinking purpose as it is not safe as it can easily get polluted by human activities and other polluting activities like erosion. Freshwater is first treated and then used for human consumption.
The rain, snow, and mist which are the precipitation from the atmosphere are the most of the source of freshwater. They contain dissolved material from the atmosphere, sea, and path from where they have traveled. In the industrial area, the rain contains most of the dissolved toxic gases.

Note:
There are many sources of water present on the earth like a river, stream, sea, ocean, etc but out of them only 3% is occupied by freshwater.Fresh water may also include water in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers, streams, and even underground water called groundwater.
Water is critical to the survival of all living organisms
