WOE 26 Segment One Streams Erode the Land

What On Earth Program 26 Agents of Erosion Segment One Streams Erode the Land This segment traces water from the point where it first strikes the earth until it enters the sea. It discusses the erosional processes of abrassion, saltation and solution while showing examples of potholes and waterfalls that result from turbulent water in high gradient streams. The segment is divided into four parts. The first three discuss high gradient "youthful" streams medium gradient "mature" streams and low gradient "old age" streams. The final part illustrates the phenomena of rejuvenation. Each part explains the creation of stream profiles. This segment also pays special attention to erosion and deposition phenomena, watershed development and our use and misuse of streams.
