Document Summary
Hydrologic cycle: the unending circulation of the earths water supply that is powered by solar energy. The steps are evaporation, condensation, precipitation, run off, percolation. Drainage basin: the area of land that contributes water to a river system. It erodes materials, transports materials, and creates erosional and depositional landforms. They are gradient, the change in elevation over a given distance; shape size and roughness; and discharge, the volume of water flowing past a particular point in a given amount of time. The higher the velocity the greater the erosion. Capacity is the maximum amount of solid particles a stream can carry, competence is the maximum size of a particle the stream can transport. Suspended load (silt, clay and mud in the water column), and bed load. A meandering stream is a stream that sweeps back and forth across the earths surface, needs to be a single channel. A braided stream is a network of interconnected streams.
