Geography is broadly divided into two main branches: Physical Geography and Human Geography. Physical geography focuses on the natural features and processes of the Earth, while human geography studies human activities and their relationship with the environment.
Physical Geography deals with the natural features of the Earth such as landforms, climate, rivers, soils, vegetation, and oceans. It studies the natural processes that shape the Earth's surface.
Human Geography studies the distribution and activities of human populations on the Earth. It examines aspects such as settlements, population, culture, economic activities, and the interaction between humans and the environment.
| Physical Geography | Human Geography |
|---|---|
| Studies natural features of the Earth. | Studies human population and activities. |
| Includes landforms, climate, rivers, soils, and vegetation. | Includes settlements, economy, culture, and population. |
| Focuses on natural processes. | Focuses on human–environment interaction. |
Thus, physical geography focuses on the Earth's natural environment, whereas human geography focuses on human activities and their relationship with the environment.
