The Physical Environment
This online physical geography textbook is for students to gain a basic understanding of physical geography. It is an introduction to the processes and patterns of the physical environment and demonstrates connections between human activities and the Earth system. The text makes physical geography dynamic through active learning and multimedia integration. Formative and summative assessments encourages student learning as they progress through the text.
