What describes a monolith in geological terms?

A monolith, in geological terms, refers to a single, massive rock formation that stands out prominently from its surroundings. The term 'monolith' is derived from the Greek words for "single" and "stone," emphasizing its characteristic of being one solid piece rather than a composed structure of multiple smaller rocks or sediments. Monoliths can be natural formations, such as cliffs or large rock outcrops, and are often characterized by their impressive height and uniform appearance. This definition aligns perfectly with the correct answer, distinguishing it from other choices that pertain to different geological concepts.
