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
Water waves are generally classified as deep-water waves or shallow-water waves. Deep-water waves are produced through oscillation, occurring when the water depth surpasses half the length of the waves. Shallow-water waves meanwhile, are generated through translation, occurring when the depth of water is less than 1/20 of the length of the waves.Full Answer >
The term "Seven Seas" historically referred to regional waters and bodies of water along trade routes. However, in some references the seas are mythical and not real water bodies. Presently, the Seven Seas refers to the seven oceans.Full Answer >
As a system of interconnected bodies of salt water, oceans cover 70 percent of the earth's surface and hold 97 percent of the planet's water supply. The five major oceans of the world are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean.Full Answer >
Bodies of water in the Middle East include the Amu Darya River, Euphrates River, Indus River, Tigris River, Persian Gulf and Nile River. The largest lake in the Middle East is Lake Urmia in northwest Iran, which has a surface area of 2,000 square miles and a maximum depth of 52 feet.Full Answer >
