Coastal Landscapes
Explain marine erosion, transport and deposition and the prescribed erosional and depositional landforms.
How to study National 5 Geography
Start from located evidence, identify the geographical process, develop each causal link and test management against the people and environments affected.
Core concepts
Concept 1
Hydraulic action and abrasion exploit weaknesses in rock; differential erosion helps form headlands and bays.
Exam cue: Identify whether the feature is mainly erosional or depositional.
Concept 2
Repeated erosion along a weakness can produce a cave, arch, stack and eventually a stump, while cliff retreat leaves a wave-cut platform.
Exam cue: State the wave or transport process at each formation stage.
Concept 3
Longshore drift transports sediment alongshore; deposition can extend a spit and may form a sand bar across a bay.
Exam cue: Use rock resistance, wave energy and sediment supply to explain location.
Risk pitfalls and guardrails
Explaining a spit without changing wind and wave direction.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Confusing a stack with a stump.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Saying the sea deposits material because it stops completely.
Guardrail: Check the command word, option, scale, location, time period and whether the evidence supports every link in the answer.
Memory anchors
Hydraulic action
Wave force compresses air in cracks and weakens rock.
Abrasion
Rock fragments carried by waves scour the cliff.
Erosion sequence
Crack, cave, arch, stack, stump.
Headlands and bays
Hard rock remains as headlands while softer rock retreats into bays.
Longshore drift
Swash moves sediment at the wave angle; backwash returns it downslope.
Spit and bar
A spit projects from the coast; a bar extends across a bay.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
