- Geography Rivers
- Erosion
- Hydraulic Action
- Force of Water
- Abrasion
- Rocks Scrape Along Bed
- Corrosion
- Rocks Dissolved in Water
- Attrition
- Eroded Rocks Smash into Each Other
- Hydraulic Action
- Transportation
- Solution
- Soluble Particles Dissolve in Water
- Traction
- Large Particles are Pushed Along Bed
- Saltation
- Small Particles Bounce Along Bed
- Suspension
- Small Particles Carried by Water
- Solution
- Meanders
- Formed By Erosion + Deposition
- Formed in Middle Course
- Outtside Bend Eroded
- Inside Bend Deposition
- Ox-Bow Lakes
- River Breaks Through Land on Bend
- River Flows the Shortest Course
- Deposition Cuts off Meander
- Sinuous Bend in River
- Waterfalls
- River Erodes Soft Rock
- A Platform is Created over the Soft Rock
- This Platform Turns into a Steep Drop
- Hard Rock is Undercut By Erosion
- Vertical Erosion Causes a Plungfe Pool
- Floodplains
- Lower Course of River
- Accumulation of River Deposits
- River Covers the Floodplain in Times of Flood
- Meanders Migrate Making it WIder
- Levees
- Natural Embankments on Either Side of River
- Lower Course of River
- During Flood, Eroded Material, Deposited Over Floodplain
- Deposited Material Builds Up, Creating Levees
- Deltas
- Mouth of River
- Deposition When Flocculation Occurs
- Rate of Deposition Exceeds Rate of Sediment Removal
- Knick Points
- Sudden Break in Gradient
- Rejuventation
- Marked by Rapids
- River Terraces
- Flat Ground Runs Parallel the river
- Above Current Level of Floodplain
- Created Following a Fall in Base Level
- River Terraces
- Flat Ground Runs Parallel the river
- Above Current Level of Floodplain
- Created Following a Fall in Base Level
- Incised Meanders
- Rejuvenation
- Meander Cut Deeply into Floodplain
- Creates Steep Banks called Bluffs
- Knick Points
- Sudden Break in Gradient
- Rejuventation
- Marked by Rapids
- Potholes
- Cylindrical Holes Drilled into Bed
- Erosional
- Sediment grinds the hole (Corrasion)
- Attrition Smooths Rock in the Hole
- Braided Channels
- River Forced to Split to Separate Channels
- Variable Discharges
- Erosional
- River is Choked by Sandbars
- River is Wide compared to Depth
- Erosion
