for project 6, please provide short answers for the following:

  • Explain how slope stability is related to slope angle
  • Explain what types of events can trigger mass wasting
  • Describe the main types of mass wasting - creep, slump, translational slide, rotational slide, fall, and debris flow or mudflow - in terms of the types of materials involved, the type of motion, and the likely rates of motion
  • Explain what steps we can take to delay mass wasting, and why we cannot prevent it permanently
  • Describe the timing and extent of Earth's past glaciations, going as far back as the early Proterozoic
  • Explain the differences between continental and alpine glaciation
  • Summarize how snow and ice accumulate above the equilibrium line and are converted to ice
  • Explain how basal sliding and internal flow facilitate the movement of ice from the upper part to the lower part of a glacier
  • Describe and identify the various landforms related to alpine glacial erosion, including U- shaped valleys, aretes, cols, horns, hanging valleys, truncated spurs, drumlins, roches moutonees, glacial grooves, and striae
  • Identify various types of glacial lakes, including tarns, finger lakes, moraine lakes, and kettle lakes
  • Describe the nature and origins of lodgement till, ablation till, and glaciofluvial, glaciolacustrine, and glaciomarine sediments
  • Summarize the factors that control wave formation
  • Explain how water is disturbed beneath a wave, and how that affects the behavior of waves as they approach the shore
  • Describe the origins of longshore currents and longshore drift
  • Explain why some coasts are more affected by erosion than others and describe the formation of coastal erosional features, including stacks, arches, cliffs, and wave-cut platforms
  • Summarize the origins of beaches, spits, baymouth bars, tombolos, and barrier islands
  • Describe the origins of carbonate reefs
