What does geologically mean?
Geologically is an adverb meaning “in relation to geology.” It is used when a speaker wants to frame an event, formation, age, or change in terms of Earth’s geological processes or deep time. For example, a landscape may be described as geologically old even if it appears unchanged during a human lifetime; conversely, a place with recent human settlement can still contain rock formations millions of years old. The adverb is especially common in formal and scientific writing, including geology, archaeology, environmental science, and natural-history commentary. “Geologically speaking” is a frequent framing phrase, and other established pairings include “geologically recent,” “geologically old,” and “geologically significant.” The word is neutral rather than emotional, but its use often signals attention to large scales of time and to processes that operate far beyond everyday human experience. For readers of historical and environmental subjects, it provides a concise way to distinguish biological, historical, and human timescales from geological ones.
adverbIn relation to geology or the geological history and processes of Earth. It can also mean according to geological evidence or timescales.

On a geological clock, a human lifetime is not a frame but a single flicker.
