  • Geomorphic Processes
    • Weathering
      • Mechanical Weathering
        • Process of breaking big rocks into little rocks. Cool nights and hot days can increase how quickly this process happens.
      • Biological Weathering
        • Erosion caused by animals, plants and microbes.
      • Wear away or change the appearance or texture by long exposure to the atmosphere.
    • Mass movement
      • Sliding
        • A slide happens when a section of soil or rock suddenly gives way and moves down a rock.
      • Slumping
        • Occurs when a loosely combined section of rock moves very slowly down a slope for  a short distance.
      • Is the movement of surface material caused by gravity
    • Deposition
      • Deposition is the process where material that is transported by a river is deposited.
    • Erosion
      • The process of eroding by wind, water or other natural agents.
      • Erosion - Abrasion
        • Abrasion is the mechanical scraping of a rock surface by friction between rocks and moving particles during their transport by wind, glacier, waves, gravity, running water or erosion. 
        • Hydraulic Action
          • Hydraulic action is the erosion that occurs when the motion of water against a rock surface produces mechanical weathering.
      • Attrition
        •  Attrition is a form of coastal or river erosion, when the bed load is eroded by itself and the bed
      • Solution
        •  Corrosion/solution is when certain types of cliff erode as a result of weak acids in the sea
  • Chemical Weathering
    • The erosion caused by chemical reactions.

        • Erosion caused by animals, plants and microbes.
      • Wear away or change the appearance or texture by long exposure to the atmosphere.
  • Transport
    • Solution
      • minerals dissolved in the water and carried along in the solution
    • Suspension
      • fine light material is carried along in water
    • Traction
      • Large rocks and boulders rolled along river bed.
    • Saltation
      • small pebbles and stones bounced along river bed
