Abstract

For all introductory physical geology courses.

 

Learning Objective-driven textbook, using augmented reality to bring geology to life

With its strong readability and engaging, instructive illustrations, this trusted bestseller returns with a hybrid and streamlined focus on core principles. Earth: An Introduction to Physical Geology maintains a learning objective-driven approach throughout each chapter: The text provides students with a structured learning path, tied to learning objectives with opportunities for students to demonstrate their understanding at the end of each section. The authors’ emphasis on currency and relevance includes the latest thinking in the field, particularly in the dynamic area of plate tectonics.

 

The Twelfth Edition, Pearson Science’s first augmented reality, hybrid textbook, uses the BouncePages image recognition app (FREE on both iOS and Android stores) to connect students’ digital devices to the print textbook, enhancing their reading and learning experience. Tarbuck/Lutgens’s innovative SmartFigures feature has been expanded, adding new digital content via Project Condor, Mobile Field Trips by Michael Collier, Animated Figures, and additional tutorial videos from Callan Bentley.This edition also includes MasteringGeology, the most complete, easy-to-use, engaging tutorial and assessment tool available.

 

MasteringGeology not included. Students, if MasteringGeology is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN and course ID. MasteringGeology should only be purchased when required by an instructor. Instructors, contact your Pearson representative for more information.


MasteringGeology is an online homework, tutorial, and assessment program designed to work with this text to engage students and improve results. Interactive, self-paced tutorials provide individualized coaching to help students stay on track. With a wide range of activities available, students can actively learn, understand, and retain even the most difficult concepts.
