From water vapor in the atmosphere and ice in glaciers to all forms of liquid water in between, water sources are numerable and vary. The types of water sources depend on the state of the water.Know More
Water is highly abundant on Earth and covers a little more than two-thirds of the planet's surface. Ninety-seven percent of this water is salty and found in the Earth's oceans. Unfortunately, this only leaves 3 percent of fresh water that is fit for human consumption. Of this 3 percent, over two-thirds is frozen in glaciers and icecaps, such as those covering Greenland and Antarctica. This leaves humans about 1 percent of the water on Earth to work with, and it is found in various sources.
If freshwater is found on the surface, such as a lake or stream, it is considered surface water. Water that resides in and travels through microscopic pores in the soil and some rocks is considered groundwater, and it is only available to humans via the drilling of wells. Precipitation, or water that has evaporated from the oceans, condensed and fallen from the sky, is another source, and it replenishes surface waters. All sources of water, oceanic, atmospheric, ground and surface, are all linked and interact through the water cycle, which is the evaporation, precipitation, storage and re-evaporation of water throughout the globe.Learn more about Bodies of Water
Earth is unique in that scientists have found the planet to be the only one to have liquid water on its surface, intelligent life forms living on it, a moon that helps regulate surface temperatures, an atmosphere with 21 percent oxygen and plate tectonics, according to Space.com. Scientists believe Earth exists in a "Goldilocks zone" where conditions are just right to support life.Full Answer >
If a person compares the same amount of ice and water, ice does not have more mass than liquid water. However, the volume of the ice is greater than that of liquid water. A reason for this occurring involves the molecular structure of these two different states of water.Full Answer >
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.Full Answer >
A river delta forms by the deposition of sediments from the river when it slows to join a larger body of water. Relatively fast-moving rivers can carry huge amounts of sediment eroded from their banks, with the speed of their flow keeping the sediments from settling to the river bottom. When the river joins an ocean or other body, the slowing of the water allows the sediment to settle.Full Answer >
