1.1 EARTH MATERIALS
This book concerns the nature, origin, evolution, and significance of Earth materials. Earth is composed of a variety of naturally occurring and synthetic materials whose composition can be expressed in many ways. These include their chemical, mineral, and rock composition. In simple terms, atoms combine to form minerals and minerals combine to form rocks. Discussion of the relationships between atoms, minerals, and rocks is fundamental to an understanding of Earth materials, their properties, and the processes that produce them.
