This textbook was designed to give the students of the Maricopa Community County Colleges District a free, interactive resource to accompany the class GLG110IN: Geological Disasters and the Environment, as part of the 2020 Maricopa Open Digital (MOD) Press Grant to develop high-quality, open ebooks for the classroom and public use.

This text was developed in collaboration between Dr. Charlene Estrada (South Mountain Community College), Dr. Carolina Michel (Chandler-Gilbert Community College), and Dr. Merry Wilson (Scottsdale Community College) to better engage local students in learning hazards and issues in geosciences and environmental sciences.

This work uses a place-based pedagogy by including local examples of Arizona geology and hazards entitled “Backyard Geology” within each chapter to give students a sense of connection to the learning material. Furthermore, the text is written for a non-science major with keywords highlighted and defined within a glossary, and the text is interspersed by example images, videos, and H5P interactive assessments.
