What characterizes a cliff in coastal geography?

A cliff in coastal geography is characterized by a steep face of rock and earth, typically formed through the process of erosion. This steep vertical drop is often created by the action of waves continually pounding against the rock at the base, which can lead to significant material removal over time. As the softer rock layers erode away faster than the harder layers, a cliff face is formed, showcasing the different strata of rock that have been exposed.

Cliffs can also be influenced by other environmental factors, including weathering, geological processes, and the type of rock present. Their steep nature makes them distinctive features along coastlines, contrasting sharply with gentler shorelines such as sandy beaches or gradual slope areas.
