Geologic evolution refers to a system of changes within a geological system. An example would be studying how a specific area has changed from ocean to mountains to desert over a period of time.
Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. Earth is very old.
