The changing rates of erosion of different rock types is known as differential erosion Flashcards
1
Q
Where there are layers of alternating rock types (strata) this creates a cliff profile where
A
the more resistant rock layers jut out due to the faster erosion of less resistant rock
2
Q
Permeability can also impact on the rate of erosion:
A
Where permeable rock overlies impermeable rock, the permeable rock is vulnerable to mass movement because the additional weight and lubrication the water creates leads to instability
3
Q
differential erosion
A
causes complex coastlines
