There is one substance in this world that is the essence of life – Water. We all depend on water, says Green Water Technologies, and water is everywhere. In fact, 70 percent of our planet is covered in water and nearly 70 percent of the human body is comprised of water. Humans typically need to drink at least 2 liters of water a day to enjoy maximum health.
Earth is the only planet, as far as we know, covered in liquid water. Green Water Technologies notes that water’s life-giving chemistry has nurtured life on Earth for billions of years. It’s possible that life first developed in its warm waters. From space, the beauty of our water world is beyond words. This unique water chemistry is truly special to our world.
Water exists as a gas, a liquid and a solid. Unlike other substances, which expand on heating, water expands on freezing.
Surface water is derived from a combination of ground water seeping into the surface of the earth as well as from rainfall, according to the experts at Green Water Technologies. Surface water is found in every lake, pond, stream, river and ocean on earth. Groundwater is water that’s crammed in the tiny gaps between rocks, soil, and sediments under the ground. A full body of groundwater is called an aquifer. There are huge aquifers all across America, notes Green Water Technologies, and groundwater is an important resource. Underground pockets of water are responsible for helping to irrigate large areas of land, such as those in the Western United States.
According to Green Water Technologies, salinated water found in the oceans comprises approximately 97% of the Earth’s water supply. Humans utilize saltwater every day. Saltwater is evaporated into clouds and turned into freshwater through the natural water cycle. Additionally, humans consume a large number of marine animals native to saltwater.
