How does the physical geography of South Asia impact human cultures? Write 1 paragraph (5-8 sentences).

The geographic term "Asia" was originally used by ancient Greeks to describe the civilizations east of their empire. Ancient Asian peoples, however, saw themselves as a varied and diverse mix of cultures-not a collective group. Today, the term "Asia" is used as a cultural concept, while subregion classifications describe the distinct geopolitical identities of the continent. These classifications are Western Asia, Central Asia, Southern Asia, Eastern Asia, Southeastern Asia, and Northern Asia.
