Physical geography is the branch of geography that studies the Earth's natural surface environment. It investigates the spatial patterns and processes of the lithosphere, hydrosphere, atmosphere, pedosphere, and biosphere. This academic field examines the formation, distribution, and interaction of physical features and systems, such as landforms, climate zones, water bodies, soils, and ecosystems, often employing scientific methods and geospatial technologies. Its significance lies in providing crucial understanding of environmental dynamics, natural hazards, resource management, and global environmental change.
