Mineralogy
Dexter Perkins et al. · University of North Dakota
Minerals are our planet. They form the Earth and the bedrock that we live on, making up all of Earth’s rocks and sediments, and they are important components in soils. So, they literally are the foundations for our lives. Perhaps because they are ubiquitous, most people don’t even notice them or consider that all rock is made of minerals.

Our World Ocean: Understanding the Most Important Ecosystem on Earth
W. Sean Chamberlin, Nicki Shaw, and Martha Rich · Fullerton College
This book offers an alternative to the traditional, dry-as-bones, hohum approach of the standard textbook. Sure, it covers all the topics you’ll find in a traditional oceanography textbook. But that’s just the tip of the iceberg. We go broader and deeper. We write the way people talk— conversationally. We encourage folks to interact with the text, to click through to full-size images, to view video and hear audio, and to quickly access the reference materials.
