1. What are the four ways that a river erodes a landscape?
Erosion happens via Abrasion, Attrition, Hydraulic Action & Solution
2. Define/explain one of these erosional forces.
Abrasion: causes river bed to become deeper through the action of scraping or wearing away
Attrition: stones and rocks knock together breaking into smaller particles so the bedload is breaking itself apart or by hitting the bed
Hydraulic Action: the ability of moving water to dislodge and transport rock particles, breaking up the banks
Solution: Water dissolved soluble materials
3. List two ways humans try to manage river flow?
Dams, reservoirs, levees, dykes, hydroelectric power stations, dredging
4. List two depositional landforms a river creates.
Alluvial Fan, delta, braided channel, oxbow lake, flood plain, sand/point bar, natural levee
5. What are the two ends of a river called?
source- the start
mouth - end
