Other questions in this quiz

2. What is a glacier's relationship with the surface gradient?

  • It's flow changes it
  • It flows parallel to it
  • It flows against it

3. As Ice flows over a gentler gradient it decelerates and backs up, creating an area of:

  • Compressing
  • Extending

4. Why do the centre and surface of a glacier move faster than the sides and base?

  • Due to climate change
  • Due to friction from the surrounding valley
  • Due to pressure melting point

5. As Ice flows over a steeply sloping bed, movement is likely to speed up, resulting in a thinner glacier with crevasses – an area of:

  • Extending flow
  • Compressing flow
