Physical geography is the study of natural features and phenomena on the planet's surface and our interactions with them. These features include vegetation, climate, the local water cycle, and land formations. Geography doesn't just determine whether humans can live in a certain area or not, it also determines people's lifestyles, as they adapt to the available food and climate patterns. As humans have migrated across the planet, they have had to adapt to all the changing conditions they were exposed to.
