Cold Environments

1. 1What is Dynamic Equilibrium?

   1. AWhere landforms and processes require water and ice to create a system.
   2. BWhere landforms and processes are in a state of balance.
   3. CWhere there are no inputs and no outputs.
2. 2Which explanation best suits the dynamic equilibrium in a glacial system?

   1. AIn a glacial system, an equilibrium line can be drawn to mark the boundary between the accumulation zone (Inputs) and the ablation zone (outputs).
   2. BThe equilibrium line is when the outputs and inputs are both extremely high meaning that the equilibrium line is also extremely high.
3. 3What is the glacial system?

   1. AA glacier can be viewed as an open system- with inputs from and outputs to external systems.
   2. BA glacier can be viewed as a closed system.
4. 4What is the main input in a glacial landscape?

   1. ARain
   2. BSnow
   3. CSleet
5. 5What is the main output in a glacial system?

   1. ALiquid water
   2. BIce
   3. CSnow
   4. DSleet
6. 6What are the stores/components in a glacial system?

   1. ARocks and landforms
   2. BSnow and Ice
   3. CDeposition
   4. DSystems
7. 7What are the flows and transfers in a glacial system?

   1. AAbrasion/ attrition
   2. BEvaporation/ sublimation
   3. CFreeze thawing
   4. DGlobal warming
8. 8What is a feedback loop?

   1. AIt has both positive and negative feedbacks which perform regulatory functions working to establish balance and equilibrium.
   2. BWhen a system has had a shift in the equilibrium line and this has meant that there is a need for more input than output to ensure the continuation of the glacier.
   3. CThe stores and components have recently been refreshed by an input and therefore the equilibrium line has remained the same.
