Geography is the study of Earth and its features. Geographers study natural features of our world, such as climate, soil, mountains, and waterways. They also study how human populations use Earth. Recognizing differences in geography can help you understand how people adapt to the land where they live and how they change tho land. Maps are one of the tools geographers use to represent information about natural features and human populations. As you read, consider how humans have interacted with the world and changed it.
In this chapter you will study these topics:
