What is a steep cliff between higher and lower land?

A steep cliff between higher and lower land is often referred to as a "bluff" or "precipice." These geological formations are typically characterized by their vertical or near-vertical faces, which can result from erosion, geological uplift, or the effects of weathering. Cliffs can be found in various landscapes, including coastal areas, mountains, and river valleys, and they often provide dramatic views and unique ecosystems.
