Snow and perennial ice

Review test

 

  1. How does snow influence the biotic environment?
    Go back to Alpine snow
     
  2. What influence on snow distribution does continentality have?
    Go back to Spatial distribution
     
  3. The elements Na and Cl are dominant in a snowpack (meltwater) analysis in the French Alps. Also the Ca-value is high. Explain the origin of these chemical elements in the snowpack. Which other elements are often found in meltwater analysis?
    Go back to Chemical characteristics
     
  4. Write the energy balance equation and explain the different components and their influence. In addition explain other energy fluxes within and under the glaciers.
    Go back to Energy and mass balance
     
  5. Explain the difference between cold, polythermal and temperate glaciers. Give examples of areas, where these glacier types occur.
    Go back to Ice formation and firn facies
     
  6. Which factors determine the ground temperatures in permafrost environments?
    Go back to Thermal conditions
     
  7. Which ice forms in permafrost ground can you name? Explain the differences between the syngenetic and epigentic freezing process.
    Go back to Ice content
     
  8. Explain the process chain between climate and glacier.
    Go back to Cryosphere scheme and models
     
  9. Why is snow cover an important factor in the climate-permafrost relationship?
    Go back to Snow permafrost glacier interactions
     
  10. Explain the flow of a glacier and draw a scheme with a typical vertical flow profile
    Go back to Flow and temperature
