How do cliffs form
Webcliff, steep slope of earth materials, usually a rock face, that is nearly vertical and may be overhanging. Structural cliffs may form as the result of fault displacement or the resistance of a cap rock to uniform downcutting. Erosional cliffs form along shorelines or valley walls where the most extensive erosion takes place at the base of the slope. WebWaves attack base of cliff, via abrasio and hydraulic action. Creates a wave-cut notch which is undercut. This becomes unstable and collapses. Notch migrates inland and cliff retreats. Wave cut platform is smoothed via abrasion and solution.
