Coastal deposition results in the formation of

Step 1: Analyze the question The question asks which landform is produced by deposition (the laying down of material) along the coast, not by erosion.

Step 2: Explain the concept Waves do two main things along a coastline:

• Erosion wears away the land. It produces cliffs, wave-cut platforms, caves, arches, stacks, and stumps.
• Deposition happens when waves lose energy and drop the sand, shingle, and pebbles they are carrying. It produces beaches, spits, bars, and tombolos.

Step 3: Check each option

• A. Stack: an erosional feature. It is a isolated rock column left when the top of an arch collapses.
• B. Arch: an erosional feature. It forms when waves cut through a headland and a cave breaks through to the other side.
• C. Pillar: this is another name for a stack, so it is also erosional.
• D. Beach: a depositional feature. It is an accumulation of sand and pebbles laid down by waves.

Step 4: Answer Only the beach is formed by deposition.

Step 5: Exam tip Remember the erosion sequence "Cave → Arch → Stack → Stump." Anything in that chain is erosion. For deposition, think of material being built up: beach, spit, bar, tombolo.
