From the Greek for 'pan', meaning all or entire and 'gaea', meaning earth.
earth in roman mythology is Terra and in Greek mythology it is Gaea
The Greek word "geography" is derived from "geo" meaning earth and "graphia" meaning to write or describe. Therefore, geography originally meant to describe or write about the Earth's features, such as its landscapes, climates, and cultures.
The root word for geographical is "geo," which comes from the Greek word meaning "Earth."
