Why is "Confusing headland and cliff" a common mistake in Formation of Coastal Landforms Part 1?

Why it happens: Both are rocky features at coasts. How to avoid it: HEADLAND = piece of land projecting OUT into the sea. CLIFF = vertical rock face. A headland often HAS a cliff face but they're not the same. Source: 0460 Examiner Reports 2022-2024

Why is "Skipping the arch stage when describing cave-stack sequence" a common mistake in Formation of Coastal Landforms Part 1?

Why it happens: Stages blur. How to avoid it: Cave → ARCH → stack → stump. Five clear stages. Mark scheme tests recall of all five.

Why is "Calling a wave-cut platform a beach" a common mistake in Formation of Coastal Landforms Part 1?

Why it happens: Both are flat coastal features. How to avoid it: BEACH = depositional, made of sand/pebbles. WAVE-CUT PLATFORM = erosional, exposed bedrock at base of retreating cliff.

Coastal Landforms Part 1 (Erosional) Study Notes — Cambridge IGCSE Geography 0460 (2024-2026 syllabus)

Headlands and bays. Cliffs and wave-cut platforms. The classic cave-arch-stack-stump sequence. Process-led explanations of erosional coastal landforms.

What you’ll learn

Mapped to the Cambridge IGCSE 0460 syllabus (2024-2026).

2.2.1 — Explain headlands and bays.
2.2.2 — Describe cliff and wave-cut platform formation.
2.2.3 — Describe cave-arch-stack-stump sequence.

Headlands and bays

Differential erosion — hard rock survives, soft rock erodes.

Coastlines often have alternating bands of HARD and SOFT rock running perpendicular to the coast.

Soft rock erodes faster (via hydraulic action + abrasion), creating BAYS curving inland.

Hard rock erodes slowly, sticking out as HEADLANDS into the sea.

Once formed, headlands face concentrated wave attack on three sides (front, both flanks). Wave refraction brings extra energy to the headland — accelerating its eventual erosion into caves, arches, etc.

Examples. Dorset coast UK (Old Harry Rocks, Lulworth Cove area).

Cambridge tip. Mark scheme expects: ALTERNATING rock bands + DIFFERENTIAL erosion + named processes.

Alternating hard/soft rock.
Soft → bay; hard → headland.
Wave refraction concentrates energy on headlands.

Cliff and wave-cut platform

Wave erosion at base → cliff retreats inland → platform exposed.

Step 1: Wave-cut notch. Destructive waves erode the base of the cliff via hydraulic action and abrasion, carving a NOTCH.

Step 2: Undercut and collapse. As the notch deepens, the overhanging cliff becomes unstable. GRAVITY pulls it down — the cliff face COLLAPSES.

Step 3: Repeat — cliff retreats. The fallen debris is gradually removed by waves. The base is eroded again; the cycle continues. Over centuries, the cliff RETREATS landward.

Step 4: Wave-cut platform exposed. A flat rocky shelf is left at the base of the retreating cliff. Visible at LOW TIDE. Often has rock pools.

Cambridge tip. Mark scheme rewards labelled cross-section showing notch → undercut → collapse → retreat → platform.

Notch → undercut → collapse → retreat.
Platform exposed at base.
Visible at low tide.

Cave → arch → stack → stump

Classic five-stage erosion sequence on a headland.

Crack → cave → arch → stack → stump — Cambridge's all-time favourite coastal landform question.

1. Crack. Natural weaknesses (joints, faults) in the headland are wider points for wave attack.

2. Cave. Hydraulic action and abrasion widen the crack into a CAVE.

3. Arch. Erosion continues; the cave breaks through to the other side of the headland, forming an ARCH.

4. Stack. The arch's roof becomes unstable as it widens. It eventually COLLAPSES, leaving an isolated pillar — a STACK.

5. Stump. Continued erosion at the stack's base topples it. What remains, often visible only at low tide, is a STUMP.

Examples. Old Harry Rocks (Dorset UK), Twelve Apostles (Australia — though many have now eroded to stumps).

Cambridge tip. Five stages, all named. Mark scheme rewards labelled diagram with arrows.

5 stages: crack, cave, arch, stack, stump.
Each progresses by hydraulic action + abrasion.
Diagrams strongly rewarded.

Step-by-step worked examples — Formation of Coastal Landforms Part 1

Step-by-step solutions to past-paper-style questions on formation of coastal landforms part 1, written exactly the way a tutor would explain them at the board.

1Formation of headlands and bays (6 marks)
Extended• Adapted from 0460/12 Oct/Nov 2024• headlands
Question
Explain the formation of headlands and bays. (6 marks)
Step-by-step solution
1. Step 1
  Differential erosion (2 marks). Coastlines often have alternating bands of HARD and SOFT rock running perpendicular to the coast.
2. Step 2
  Soft rock erodes faster (2 marks). Wave erosion (hydraulic action, abrasion) wears away soft rock more quickly, creating BAYS that curve inland.
3. Step 3
  Hard rock resists (2 marks). Bands of hard rock erode more slowly, sticking out into the sea as HEADLANDS.
Answer
Alternating hard/soft rock → soft erodes fast (bays) → hard erodes slowly (headlands).
2Cliff and wave-cut platform (6 marks)
Extended• cliff
Question
Describe the formation of a cliff and wave-cut platform. (6 marks)
Step-by-step solution
1. Step 1
  Wave attack at base (2 marks). Destructive waves erode the base of the cliff via hydraulic action and abrasion, creating a WAVE-CUT NOTCH.
2. Step 2
  Cliff retreat (2 marks). As the notch deepens, the overhanging cliff becomes unstable and COLLAPSES under gravity. Process repeats; cliff RETREATS LANDWARD.
3. Step 3
  Wave-cut platform (2 marks). As the cliff retreats, a flat rocky surface is exposed at the base — the WAVE-CUT PLATFORM. Visible at low tide.
Answer
Wave erosion → notch → undercut → collapse → retreat → exposes platform.
3Cave-arch-stack-stump sequence (8 marks)
Extended• coastal-erosion
Question
Describe the sequence of cave → arch → stack → stump on a headland. (8 marks)
Step-by-step solution
1. Step 1
  Headland weak points (2 marks). Joints, cracks, and faults in the headland are eroded faster by waves.
2. Step 2
  Cave (2 marks). Wave erosion (hydraulic action) widens cracks into a CAVE in the headland.
3. Step 3
  Arch (2 marks). Cave erodes through to the other side, creating an ARCH.
4. Step 4
  Stack (1 mark). Arch roof collapses (gravity, wave erosion), leaving an isolated pillar — a STACK.
5. Step 5
  Stump (1 mark). Stack erodes at the base, eventually toppling. Remaining short pillar is a STUMP, often visible only at low tide.
Answer
Crack → cave → arch → stack → stump. Each stage marks progressive erosion of weakness in the headland.
Examiner tip
Cambridge classic question. Mark scheme rewards labelled diagram showing all five stages.
