Snow and perennial ice

Learning Objectives

 

 

  • release virtual avalanches
     
  • melt snow
     
  • compare temperature measurements in permafrost and estimate their significance
     
 

  • recognize which (re)distribution factors have influenced snow depth at a particular place
     
  • name and characterize the different zones of a glacier
     
  • describe permafrost phenomena with an appropriate terminology
     
  • distinguish between different ice forms
     
  • interpret temperature measurements in relation to permafrost
     
  • specify the interactions between climate, glaciers and permafrost

 

  • how snow flakes form
     
  • why snow melt shows typical patterns
     
  • the differences between snow and ice
     
  • why heat flux through snow and ice differ
     
  • which parameters are important for the energy and mass balance of a glacier
     
  • how temperature influences the flow of glaciers
     
  • why the occurrence of permafrost and glaciers depends on continentality
     
 

  • name 3 influences of snow on the biotic environment
     
  • find the reasons for different snow distribution patterns
     
  • estimate the duration of snow cover in a specific region
     
  • list what snow contains
     
  • distinguish snow age and content by its density
     
  • estimate how much radiation penetrates into snow under changing conditions
     
  • draw ice covered areas and different ice types onto a world map
     
  • explain how the freezing process works and how a specific ice form has developed
     
  • interpret a creep curve
     
  • recognize global change influences on permafrost and glaciers
     
  • describe the impact of the changing state of glaciers and permafrost on the alpine environment
