Document Summary

Describe how streams and rivers shape the earth"s surface. Discuss the factors that affect a stream"s velocity. Discuss competency and capacity with respect to streams. Explain the types of materials a stream can carry. Describe the difference between meandering and braided streams. Define cut bank, point bar, and thalweg. Define base level and the two different types of base levels. Explain what happens if the base level changes (up or down) Unending circulation of earth"s water, powered by solar energy. Drainage basin: area of land that contributes water to a river system. Watershed: area of land containing network of streams draining toward a common point. May have interconnected streams (looks similar to branches on a tree) All rivers/streams are defined as water flowing in a channel. Streams/rivers are the most important agent of erosion. Capacity: maximum amount of particles a stream can carry. Competence: maximum particle size that a stream can transport. Suspended load: fine particles (silt, mud, clay)
