Geography (from Greek: γεωγραφία, geographia. Combination of Greek words
‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description")
is a field of science devoted to the study of the lands, features,
inhabitants, and phenomena of Earth. The first recorded use of the word
γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC).
Geography is an all-encompassing discipline that seeks an understanding of
Earth and its human and natural complexities—not merely where objects are, but
also how they have changed and come to be. While geography is specific to
Earth, many concepts can be applied more broadly to other celestial bodies in
the field of planetary science.
