QUESTION 2

A watershed is a ridge of high land dividing two areas that are drained by different river systems. (1) And erosion is the carrying away or displacement of solids (sediment, soil, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms. Erosion is distinguished from weathering, which is the process of chemical or physical breakdown of the minerals in the rocks, although the two processes may be concurrent. (2) Streams are usually very small while rivers are larger. And lakes can also very in size.

There are about 326 million cubic miles of fresh water enough to fill the United States with a lake 90 miles deep. 70 percent of fresh water is locked in ice caps though. While less than 1 percent of the world’s freshwater is readily accessible. Though the Earth is covered in most parts with water, 72 percent of surface area, but 97 percent of the water is salty and not suited for drinking. (3) The Water quality in both ground Water and surface systems is impacted by land use decisions because of how much waste people are dumping into the rivers lakes and streams. And because of how much waste people are dumping in landfills or because of fertilizers being used to much.
