Equilibrium Flashcards
1
Q
Causeway complex cliff profile
A
Laterite - basalt - laterite - basalt
2
Q
Water infiltration?
A
Goes through laterite - porous
Stops at basalt - impermeable
3
Q
Mass movement
A
Basalt undercut by marine processes
Laterite saturated with rain (heavy)
Lubricated bedding plane
= stress > strain
4
Q
Wave cut platform
A
Material fall to make wave cut platform - absorbs wave energy
Material broken down + used for attrition
5
Q
Cliff retreat
A
Process repeats: waves attack cliff, wave cut notch, cliff retreats
Waves can’t reach cliff - equilibrium
Changes with isostatic/eustatic change
