⚖️ Erosional vs Depositional Landforms — Side by Side

Landform Type Dominant Process UK Example Key Exam Point
Wave-cut platform Erosional Abrasion + hydraulic action at cliff base Robin Hood's Bay, Yorkshire Width shows how far cliff has retreated
Headland and bay Erosional Differential erosion — soft rock erodes faster Lulworth Cove, Dorset Caused by geology, not just wave energy
Cave → arch → stack → stump Erosional Hydraulic action exploiting joints Old Harry Rocks, Dorset; Durdle Door Sequence must be explained in order
Beach Depositional Constructive waves; longshore drift Chesil Beach, Dorset Protects cliff behind; seasonal changes
Spit Depositional Longshore drift past change in coastline direction Spurn Head; Hurst Castle Spit Curved tip due to wave refraction
Bar Depositional Spit extending across a bay; longshore drift Slapton Sands, Devon Encloses a lagoon behind it
Tombolo Depositional Deposition connecting mainland to island Chesil Beach / Portland Can isolate islands from wave energy

Practice Questions for Coastal Processes and Landforms

Which of the following best describes a destructive wave?

  • A. A wave with strong swash, weak backwash and low height that deposits material on a beach
  • B. A wave with strong backwash, weak swash and tall, steep profile that erodes the coastline
  • C. A wave that only forms in sheltered bays and builds up sandy beaches over time
  • D. A wave with equal swash and backwash that neither erodes nor deposits material

Quick Recall Flashcards

What is longshore drift?
Waves approach the beach at an angle, moving sediment along the coast in a zigzag pattern. Swash moves material up at an angle; backwash pulls it back at 90 degrees.
What is attrition?
Rocks and pebbles carried by waves knock against each other, breaking into smaller, rounder, smoother fragments over time.
