1. The characteristics of extreme environments

Geographic inquiry: Why some places are considered to be extreme environments

  • Global-scale distribution of cold and high altitude environments (polar, glacial areas, periglacial areas, high mountains in non-polar places) and hot arid environments (hot deserts and semi-arid areas)
  • Relief and climatic characteristics that make environments extreme, including unreliability and intensity of rainfall in arid environments and the risk of flash floods
  • How relief, climate, human discomfort, inaccessibility, and remoteness present challenges for human habitation and resource development
    • Detailed examples for illustrative purposes
  • The changing distribution of extreme environments over time, including the advance and retreat of glaciers and natural desertification on facebook
