Erosion Erosion = the transport of sediments from weathering. *Gravity and Water are biggest factors* 1. Streams 2. Glaciers 3. Landslides 4. Waves

Streams Running water carries sediment downstream Scours bedrock Carves V-shaped gorges.

Stream Erosion
4
Vocabulary Suspended Load = particles suspended in stream. Bed Load = particles rolling on bottom (abrasion polishes rocks). Discharge = amount of water flowing past a given point.
5
Sheet Erosion = flows in sheet over flat land.
6
Rill and Gully

Stream Evolution 1.Youth = head, high elevation, steep slope, rapid erosion, V-shaped valley 2.Middle Age = Small streams merge to form tributaries, gentler slopes, stream begins to meander.
9
Old Age Gentler slope, meander widens, reaches mouth. Mouth = where stream meets ocean or lake. Sediment deposits form delta or alluvial fan.
