There is no recognized geographical classification system. In western Europe, geography is divided into two parts: general geography (that is, departmental geography) and thematic geography (that is, regional geography). General geography is divided into physical geography and human geography, and the two branches are divided into secondary branches.

The former Soviet Union divided geography into two branches: physical geography and economic geography, and then it was divided into two branches.

Western scholars divide geography into two parts: physical geography and human geography, or into three parts: physical geography, economic geography and human geography, and then into two branches.
