Physical Geography

Physical geography focuses on geography as an Earth science (and is sometimes called Earth System Science).

Physical geography is a branch of geography that focuses on the study of the natural features and processes of the Earth’s surface. It includes the examination of landforms, climate, vegetation, soils, and water resources. Physical geographers use a range of scientific methods and tools to analyze and understand the complex interactions between the Earth’s physical systems.

Learn about the different branches of geography that fall under the physical geography category: climatology, geomorphology, biogeography, and more.
