,1. MATTER AND MINERALS
INTRODUCTION
Matter and Minerals presents the fundamental characteristics of earth materials. The chapter begins
with minerals and how they are defined, then delves deeper to review the building blocks of minerals:
atoms and atomic particles. From there, the main types of ionic bonding are presented.
The final section in the chapter steps back to look at mineral properties, how minerals are identified, and
the main mineral groups.
