Q1) What is a cliff?

A cliff is a vertical or near-vertical geological feature characterized by a steep, abrupt face of rock, soil, or other material. Cliffs can be found in various landscapes, including coastlines, mountains, plateaus, and canyons. They are often formed by the erosional forces of water, wind, ice, or tectonic activity over long periods of time.
