The central question of this textbook is how to understand the evolution of Earth and life through time. Authors Wicander and Monroe provide a comprehensive overview of both the physical and biological history of our planet, detailing the inter-related events that have shaped it. They explain the historical development of key geological principles and processes, emphasizing their role in deciphering Earth's past. The text is structured around three core themes: time, evolutionary theory, and plate tectonics, which serve to unify the material and provide a framework for understanding historical geology.

This textbook is designed to teach students the fundamental principles of Earth's physical and biological history. It aims to provide a clear understanding of how scientists interpret geological evidence and reconstruct past events. The integration of core themes like time, evolution, and plate tectonics is intended to create a cohesive learning experience. The inclusion of interactive CD-ROM material suggests a focus on engaging students with the subject matter.
