ONE Headlands are usually made of resistant rocks that have weaknesses like cracks. 1 of 7 Headlands, are eroded to form caves, arches stacks and stumps. TWO Waves crash into the headlands and enlarge the cracks- mainly by hydraulic power and abrasion. 2 of 7 Headlands, are eroded to form caves, arches stacks and stumps. THREE Repeated erosion and enlargement of cracks causes a cave to form. 3 of 7 Headlands, are eroded to form caves, arches stacks and stumps. FOUR Continued erosion deepens the cave until it breaks through the headland forming an arch. 4 of 7 Headlands, are eroded to form caves, arches stacks and stumps. FIVE Erosion continues to wear away the rock supporting the arch, until it eventually collapses. 5 of 7 Headlands, are eroded to form caves, arches stacks and stumps. SIX This forms a stack- an isolated that's seperate from the headland. 6 of 7 Headlands, are eroded to form caves, arches stacks and stumps. SEVEN The stack is eventually worn away to give a stump, which can be covered by water at high tide. 7 of 7
