WebThe cliff face above the cave can erode and collapse over a period of time, creating a geo (forming a blowhole) or extending the geo deeper into the cliff. How are geos and blowholes formed? Hydraulic action and solution weaken and exploit fissures in the headland. Abrasion and corrasion then break pieces of the cliff off until a cave is formed. WebWell, cliffs are eroded at the cliff base by abrasion. The rocks within the ocean waves carve out a curve at the base of the cliff, called a wave cut notch. This eventually causes the cliff to collapse above the wave cut notch as it becomes unstable due to a lack of support at the base, leaving behind a steep cliff face.
