• Successful Presentations will include:• An annotated diagram of the feature.
• A step by step guide to share with the class on how the feature is formed.

Caves, arches, stacks and stumps
1. The waves erode FAULTS (cracks) in the headland.2. The waves eventually erode through the
headland to form an ARCH.
3. The arch becomes unsupported and collapses to form a STACK.
4. A STUMP is formed from the collapsed stack.
