QUIZZES // Coasts: weathering and erosion of cliffs
Q1. What percentage of the world’s coastline do you think is made up of cliffs?
8%
18%
80%
100%
Q2. Which one of these types of equilibrium describes the state of a coastal system where change is minimal from year to year?
Steady state equilibrium
Meta-stable equilibrium
Dynamic equilibrium
Closed system
Q3. Coastal systems and coastal morphology take time to respond to changing conditions. Which one of these terms is used to describe the period required for the adjustment to occur?
Positive feedback
Sediment pathway
Evolution
Relaxation time
Q4. Which one of the following is the best description of physical weathering?
The decomposition of rock
The disintegration of rock
The destabilisation of rock
The downwearing of rock
Q5. ‘Weathering is the loosening and breaking down of rock in situ.’ Which one of the following best explains what in situ means?
For the time being
In the original position
From the start/from the beginning
From the depths/from the deepest part
Q6. Which one of the following is a chemical weathering process, rather than a mechanical (or physical) one?
Freeze-thaw
Wetting and drying
Chelation
Crystal growth
Q7. Which one of the following is an important factor influencing mass movement on coastal cliffs?
Water content of the slope
Wave height
Sources of sediment
Entrainment
Q8. Which one of the following is a type of marine erosion?
Saltation
Sediment cell
Hydraulic action
Longshore drift
Q9. Which one of these types of marine erosion is when sediment particles collide with each other in the waves and are broken into smaller pieces, and also rounded over time?
Attrition
Abrasion
Cavitation
Bioerosion
Q10. Which one of these would be most likely to develop with a rise in sea level?
Wider beaches in front of cliffs
Decreased erosion
Slower cliff retreat
Increased erosion at the cliff foot
Q11. Coasts are often a dynamic environment, especially when they are high energy. Which one of the following terms is used to describe coastal environments where processes are producing landform changes?
Hydrodynamic
Morphodynamic
Aerodynamic
Biodynamic
Q12. In terms of cliff sway, in what direction have cliffs been recorded moving as waves add load onto the cliff foreshore?
Downward and seaward
Upward and landward
Downward and landward
Upward and seaward
Q13. The cliff sway theory suggests that a new form of weathering may be taking place as a result of cliff movement and vibration due to wave motion. Which one of these would this be?
Increased hydraulic action from higher wave energies
Higher sea level due to cliff dip
Damage to rock inside the cliff
Increased abrasion due to increased rock falls
Q14. What is left after cliff erosion is often a horizontal or gently-sloping rocky surface. Why is it more accurate to refer to this surface as a shore platform rather than a wave-cut platform?
Because these rocky surfaces are always found at the shore
Because they are not only formed by wave erosion, but by weathering and also by bio-erosion.
Because wave erosion actually has nothing to do with their formation: they are the result of rock strata orientation
Because sea level change is likely to increase their gradient
