Notes on Usage

• "Địa sinh" is a specialized compound word from "địa" (earth, geo-) and "sinh" (life, genesis). It directly translates to "geo-genesis" or "earth-born," aligning with its meaning of things originating or existing underground.
• It is important to distinguish this from similar-sounding words. "Địa sinh" is not related to "địa lý" (geography) as a general field, but is a specific term used within it.
