Physical Geography
K. Allison Lenkeit-Meezan · Foothill College
Physical geography is the study of the earth's dynamic systems: its air, water, weather climate, landforms, rocks, soils, plants, ecosystems and biomes and how humans interact with the earth's systems. Physical geography is the study of the world around you. Everyone, every day, interacts with the earth's dynamic systems.
