Geography is the science of space and place; it also can be considered as the study of the relationships between people and their physical environment. Geography is typically broken down into two main subdisciplines: physical geography and human geography. Physical geographers study the physical environment, including climate, landforms, and, soils; human geographers, on the other hand, study things such as humankind's economic, political, and cultural systems. Geography cannot be confined to these two subdisciplines, however, as it includes so much more! Some examples include GIS (Geographic Information Systems), political geography, and economic geography. Geographers also seek to understand where things are found, why they are found where they are, and how these things develop and change over the course of time.
