1. Changes in mass balance affect the long term behaviour of a glacier. Explain:

  • Sustained positive or negative balances put the glacier out of equilibrium and will both cause the glacier to advance
  • Sustained positive or negative balances put the glacier out of equilibrium and will both cause the glacier to retreat
  • Sustained positive or negative balances put the glacier out of equilibrium and will cause the glacier to advance or retreat respectively
  • Sustained positive or negative balances put the glacier out of equilibrium and will cause the glacier to retreat or advance respectively

2. A positive regime occurs when...

  • Accumulation exceeds ablation
  • Ablation exceeds accumulation
  • Accumulation and ablation are balanced

3. A glacier is an example of what kind of system

  • Open
  • Closed
  • Functional

4. What is the key symptom of a glacier in disequilibrium with its local climate?

  • Thinning along the entire length of the glacier
  • Thickening along the entire length of the glacier
  • Thickening in the ablation zone

5. Give an example of a positive feedback loop within a glacial system

  • As the climate warms sunlight is absorbed where dark soil is exposed; light absorption speeds us warming, exposing more dark soil.
  • Ice sheets causing erosion at their bases
  • Too little precipitation means glaciers and ice fields cannot be maintained
