Mass wasting is the downslope movement of soil and weathered rock debris. Streams can deepen valleys by downcutting (erosion), but widening or enlarging of the valley via erosion of the sides or slopes is accomplished largely through mass wasting. Mass wasting delivers the weathered rock material and soil to the streams, which carry it away to some site of deposition.
An ephemeral stream is a stream that flow with water only following rain storms. The stream quickly disappears when the rain stops.
Not all are. Some stream beds are sandy, and some are rocky.
mid latitude jet stream and jet stream
well a spark stream is electricity so whatever it is it works from electricity :) x
River valleys are formed by stream erosion.
valleys are made when a stream erodes at the sides and bottom.
Stream valleys are a great place to settle since it provides you with fresh water and fertile soil for planting crops.
in stream valleys
DELTA AND TOMBOLO :p
mass wasting on the valley sides
River/stream cut valleys are 'V' shaped while Glacial valleys are 'U' shaped.
Streams that are first forming.
U-shaped valleys or cirques. Not positive.
A stream cutting its channel closer to base level leads to formation of a V-shaped valley.....:-)
