Rivers

1. Processes

   • Erosion
     • Abrasion
       • Scraping surfaces
     • Attrition
       • Collision breakdown
     • Solution
       • Rock dissolution
     • Hydraulic action
       • Water force
   • Deposition
   • Transportation
     • Traction
       • Large boulders
     • Saltation
       • Pebbles
     • Suspension
       • Small rock particles
     • Solution
       • Dissolved rocks that are acids

2. Parts

   • Source
   • Tributaries
   • Confluence
   • Meander
   • Delta
   • Mouth

3. Meanders

   • Inside curve
     • Most enegry
     • Erosion
   • Outside curve
     • Least energy
     • Deposition
   • Oxbow lakes
     • Bend gets sharper
       • In a flood the bend gets cut off
         • It forms an oxbow lake and then eventually dries up

4. Examples

   • River Ganges
     • India/Bangladesh
   • River Volga
     • Russia
   • River Yangtze
     • China
