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
The four types, or processes, by which a river erodes are hydraulic action, abrasion or corrasion, attrition and corrosion. Each process affects the river in different ways.Full Answer >
Ocean water is moved by three different forces: waves, currents and tides. These forces cause ocean water to move around the vast area that the ocean covers.Full Answer >
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 >
Rivers are the primary body of water found in tropical rainforests. Many rainforests feature one large river that feeds the entire ecosystem and many smaller rivers that drain into the major water body, such as the Amazon river and its many tributaries.Full Answer >
