Water comes from three main natural sources: rain water, underground water and surface water. Rain water includes rain, snow and other forms of precipitation. Underground includes water tables and water hidden in the soil. Surface water includes oceans, rivers, lakes, ponds and any other above-ground collection of water.Know More
These natural sources of water supply most of the water for the planet. Precipitation replenishes underground and surface water supplies and is a key part of the water cycle. Underground water sources are not immediately accessible but are one of the most important sources of water for human consumption. Underground water supplies are accessed through wells, or from springs when the pressure gets too great.
Surface water is the easiest to access and the most abundant, though most surface water is salt water, and, therefore, not suitable for drinking by most species. Surface water is used for drinking and for producing hydro-electric power as a renewable, clean energy source. This water comes from precipitation, springs and the melting of glaciers. Rivers eventually empty into the ocean.
A large portion of fresh water is trapped in glaciers, the ice caps and the atmosphere. The frozen water is not accessible directly by humans, but it does help to replenish surface water supplies as the global temperature rises and the ice melts.Learn more about Bodies of Water
According to Mother Nature Network, purified water can be taken from any water source and then purified to remove contaminants and chemicals. Spring water, however, is water taken from a natural spring groundwater source. Spring water may or may not have undergone water treatment.Full Answer >
Water management worldwide uses a variety of techniques, including building dams and reservoirs, digging canals and irrigation ditches and building and maintaining dyke and levee systems. The control of water flow has been integral to human civilization's development.Full Answer >
Water is important because it is one of the best solvents in nature. Living systems require solvents in order to mix various chemicals with one another, and water is the best substance for the job. According to Public Broadcasting Systems, living organisms need water because the biochemical processes of life must take place in a fluid.Full Answer >
Brackish water is water that has some salt content but not as much salt as sea water. Water that is not fresh water or salt water is called brackish.Full Answer >
