results from headward erosion of a stream catches another stream and changes the outward point. The interfluve water that was not attached to the stream is added on, lengthening the valley created by the stream.
high land above valley -> between rivers -> overland flow, Region of higher land between two rivers that are in the same drainage system. Controls water flow and direction of river.
Little to no chemical weathering because there is little rainfall, way too dry. The weathering is mostly mechanical, very slow weathering
stream flows are confined to channels. In a straight stream-fasted flow in center-friction causes drag on sides and bed of channel. Speed depends on width, depth, and roughness of the river
what happens when sediments are deposited and there's not enough energy to carry them. Flow speed drops, volume decreases, channel width (expand width, volume smaller, speed slows), change in direction (slow speeds)
within a drainage basin, smaller streams combine to make bigger streams, bigger streams combine to make even bigger streams. This is the concept, which is used to define a streams context within a drainage basin/
initial concentration of flow, The removing of thin layers of soil as little rivulets of running water gather and cut small channels in the soil.
