Ice flows
- Surges
- Meltwater builds up
under the glacier, ice
moves rapidally
forward
- 250 -
300 mm
in a day

- Hazard to those
living in glacial
valley below

- Blockschollen Flow
- Once ice is
compacted enough
to become glacial
ice, it flows like
plastic
- Once ice is

- Regelation
- Ice melts under high pressure (pressure - melt
layer), as opposed to deforming, and it refreezes
on the other side of the rock/obstacle, as a
regelation layer

- Basal slippage
- Water underneath the glacier
(a thin layer), which lubricates
it and allows it to move
- Water underneath the glacier

- Internal Deformation
- When the ice in the middle of the
glacier (where there isn't any
friction), flows further than the
edges
- The ice crystals
have lined up to
allow them to
move past
eachother

- Extending Flow
- Where gradient
increases causing ice
velocities to increase and
ice to spread out
- Where gradient
increases causing ice
velocities to increase and
ice to spread out
- Compressing Flow
- Where gradient
decreases causing ice
velocities to slow and ice
to build up
- Where gradient
decreases causing ice
velocities to slow and ice
to build up
