Weathering and Formation

Subdecks (3)

Cards (16)

  • In situ
    No removal of solid material
  • Erosion
    Removal of weathered products by agents such as gravity, water, wind and ice
  • Weathering
    Chemical and Physical breakdown of rocks in situ
  • Mechanical/Physical Weathering
    Leads to disintegration of the bedrock into smaller, angular but chemically identical fragments
    Results in an increase in the surface area of rock exposed for chemical weathering to act upon
  • Mechanical/Physical Weathering
    Leads to disintegration of the bedrock into smaller, angular but chemically identical fragmentsLeads to disintegration of the bedrock into smaller, angular but chemically identical fragments
    Results in an increase in the surface area of rock exposed for chemical weathering to act upon
  • Chemical Weathering
    Leads to the decomposition of the bedrock
    Only Quartz is not affected
    Creates clay minerals from the breakdown of silicate minerals
    Ions are released into solution
  • All Silicate Minerals except quartz are unstable at the earths surface and are trying to re-adjust to the new conditions
