3. Scan 2.45 Why are
slopes important?
Evidence that this slope is currently active –
A Lot of angular fragments lying at the foot
of the slope – this is called Talus
Outcrops of bare rock, exposed to
weathering from where the material has
fallen
Absence of vegetation – plants will only
colonise a stable area further stabilising it.
4. Why is the slope unstable?
Four Clues –
Slope very steep
Road has cut into the base
No infiltration – no vegetation
Traffic Vibrations
5. How steep is steep?
Match the angles with the limiting factors.
Define Land use.
