  • What is the wearing away of the earth's surface by natural processes involving agents?
  • List the agents of erosion which act to lower land to base level?
  • What is the breakdown of existing surface and near surface material?
  • What are the two classes of weathering?
  • Which class of weathering is considered disintegration?
  • Which class of weathering acts to break the pieces into smaller pieces without changing the composition of the material?
  • Which type of mechanical weathering occurs when the water in cracks freezes and expands and cracks the rock?
  • Which type of mechanical weathering occurs when water evaporates and crystals grow in cracks and breaks the rocks?
  • Which type of weathering causes the rocks to peel like an onion and is especially active against intrusive igneous bodies and accelerated by chemical weathering?
  • Which type of mechanical weathering is caused by the growth of plant roots cracking the rocks?
  • What other influences may cause mechanical weathering?
  • Which type is BEST exemplified by Stone Mountain, Georgia and Half Dome in Yosemite?
  • What type of weathering involves the breaking of rock as chemical changes make the materials weaker?
  • What type of weathering is considered decomposition?
  • What type of chemical weathering involves acidic ground water acting on the materials in the chemical process based upon CO2 + H2 H2CO3 or carbonic acid?
  • What type of chemical weathering is like the rusting of rocks?
  • What type of chemical weathering occurs when water joins the mineral components to cause expansion or swelling of the materials?
  • What type of chemical weathering occurs when water joins and weakens the rocks?
  • What type of chemical weathering involves the leaching of rocks?
  • What other influences may cause chemical weathering?
  • What four factors affect the rate of weathering?
  • How does the nature of the rock affect the rate of weathering?
  • How does the size of the particles affect the rate of weathering?
  • How does the climate affect the rate of weathering?
  • How does the topography affect the rate of weathering?



    What two terms are used for the process associated with the agent of erosion called gravity?
  • What is the downslope movement of solid and solid and liquid material under the influence of gravity?
  • What are the three variables that influence identification of the types of mass wasting or mass movements?
  • What type of mass movement involves large chunks of bedrock falling from a steep slope?
  • What type of mass movement involves chunks of snow and ice moving down a slope?
  • What type of mass movement involves masses of materials falling quickly down a slope?
  • What type of mass movement involves water and material flowing down a slope like a river of mud and materials?
  • What type of mass movement involves material gradually falling off of a slope and accumulating as a pile at the base?
  • What type of mass movement involves material slipping downward along a surface?
  • What type of mass movement involves material on a slope slowing and gradually moving down the slope?
  • Which type of mass movement is often seen along expressway embankments?
  • Which type of mass movement is evident from old tombstones on cemetery hillsides?
  • Which type of mass movement involves slow downslope movement of saturated soil at high latitudes?
