The physical geography of Earth is explained through the systems that shape the planet''s lands, waters, and atmosphere. Written in an easy narrative style, each chapter combines text with more than 40 single-concept illustrations. The result is a distinctive design that weaves words and illustrations together into an integrated whole. The presentation is uncluttered to keep students focused on the main themes. An entire chapter is dedicated to climate change, its geographic origins, likely outcomes, and influence on other Earth systems. A distinctive illustration program includes summary diagrams at the end of chapters that recap concepts and reinforce the systems approach. Section summaries within chapters, along with end-of-chapter review points and questions, are provided to highlight key concepts and encourage thoughtful review of the material. The instructor''s guidebook highlights the core concepts in each chapter and suggests strategies to advance a systems approach in teaching physical geography.
