What part of geography focuses on the earths natural landscape and physical systems

Physical geography focuses on geography as a form of earth science. It tends to emphasize the main physical parts of the earth – the lithosphere (surface layer), the atmosphere (air), the hydrosphere (water), and the biosphere (living organisms)—and the relationships between these parts.

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
