What are the divisions of Geography?

Geography is the study of the earth's surface, climate, continents, countries, peoples, industries, and products.

Physical and Human Geography

Generally, two main branches of geography are recognized:

One that focuses on people and cultures, human geography, which encompasses such areas as population geography, economic and political geography and others and

One that focuses on the physical environment on planet earth, physical geography, which includes but is not limited to geomorphology, biogeography and environmental geography.

These two branches within geography are not studied separately.  Research usually focuses on interconnections between people AND their environment; an interdisciplinary approach which is the strength of the discipline.
