This document discusses the differences between physical geography and human geography. Physical geography is the study of natural phenomena on Earth, including lithosphere, atmosphere, hydrosphere and biosphere. It examines landforms, climate, oceans, and other physical aspects. Human geography studies how humans interact with and modify the environment through activities like agriculture, settlements, economic systems, and transportation. Both influence each other as people depend on nature for resources but alter the environment through technology. The document provides examples of topics in physical geography like rocks and minerals, and human geography like population and urban systems.
