	Physical Geography is the study of the Earth's natural features and processes. It examines the "How" and "Why" of the physical world—from the way mountains are formed and rivers carve out canyons to the patterns of weather and the distribution of plants and animals. Unlike "Human Geography" (which studies people and cities), physical geography focuses on the '''Biosphere''', '''Atmosphere''', '''Hydrosphere''', and '''Lithosphere'''. By understanding these systems, we can see how the Earth acts as a single, giant "Living Machine" that provides the foundation for all human life and activity.

Physical Geography is the study of the Earth's natural features and processes. It examines the "How" and "Why" of the physical world—from the way mountains are formed and rivers carve out canyons to the patterns of weather and the distribution of plants and animals. Unlike "Human Geography" (which studies people and cities), physical geography focuses on the **Biosphere**, **Atmosphere**, **Hydrosphere**, and **Lithosphere**. By understanding these systems, we can see how the Earth acts as a single, giant "Living Machine" that provides the foundation for all human life and activity.

* '''Physical Geography''' — The branch of geography dealing with natural features and processes.
* '''Atmosphere''' — The envelope of gases surrounding the Earth (Weather and Climate).
* '''Lithosphere''' — The rigid outer part of the earth, consisting of the crust and upper mantle (Rocks and Soil).
* '''Hydrosphere''' — All the waters on the earth's surface, such as lakes and seas.
* '''Biosphere''' — The regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.
* '''Erosion''' — The process of eroding or being eroded by wind, water, or other natural agents.
* '''Weathering''' — The wearing away or change in the appearance or texture of something by long exposure to the air.
* '''Landform''' — A natural feature of the earth's surface (e.g., Mountain, Plain, Valley, Delta).
* '''Topography''' — The arrangement of the natural and artificial physical features of an area.
* '''Hydrologic Cycle''' — The continuous movement of water on, above, and below the surface of the Earth.
* '''Glaciation''' — The process, condition, or result of being covered by glaciers or ice sheets.
* '''Ecosystem''' — A biological community of interacting organisms and their physical environment.
* '''Drainage Basin''' — The area of land where all surface water converges to a single point (usually a river or lake).
* '''Biome''' — A large naturally occurring community of flora and fauna occupying a major habitat (e.g., Tundra, Rainforest).
