-
What process allows pioneer plants to trap sediment and build stable sand dunes?
- Plant succession
- Marine abrasion
- Sub-aerial weathering
- Differential erosion
-
Which coastal ecosystem is stabilised by plant succession in low-energy estuarine environments?
- Wave-cut platform
- Sand dune
- Shingle spit
- Salt marsh
-
How does vegetation help to stabilise sandy and estuarine coastlines?
- Promotes slumping
- Increases erosion
- Increases cliff dip
- Binds sediment

- Hard igneous rock
-
Which material type generally experiences the highest rate of coastal recession?
- Metamorphic basalt
- Crystalline limestone
- Igneous granite
- Unconsolidated boulder clay
-
Which rock group is generally most resistant to marine erosion and coastal recession?
- Igneous rock
- Sedimentary rock
- Jointed chalk
- Unconsolidated material
-
What effect does an abundant sediment supply generally have on coastal recession rates?
- Increases cliff height
- Accelerates recession rate
- Reduces recession rate
- Causes mass movement
-
Which process stabilises sandy coastlines through the growth and establishment of plants over time?
- Dune succession
- Differential erosion
- Marine attrition
- Hydraulic action
-
What produces complex cliff profiles along coastlines with alternating strata of varying resistance?
- Uniform abrasion

- Differential erosion
- Constructive wave action
-
In which coastal environment does vegetation succession help trap sediment and stabilise land?
- Salt marshes
- Wave-cut platforms
- Estuarine blowholes
- Granite cliffs
-
Which term describes the physical characteristics of rock, such as hardness and mineral composition?
- Topography
- Morphology
- Lithology
- Stratigraphy
-
Why is forecasting coastal recession rates vital for local management authorities?
- Increases sediment supply

- Prevents wave formation
-
Which mass movement process commonly occurs when saturated rock overlies impermeable clay?
- Soil creep
- Rotational slumping
- Rock fall
