Root Explanation

Quartzite is formed from "quartz" (from German *Quarz*, meaning a type of hard mineral) and "-ite" (a suffix used in geology to denote rocks or minerals). The word "quartzite" refers to a hard, metamorphic rock that is primarily composed of quartz grains.

Memory Tip

Think of 'quartz' as a hard mineral and '-ite' indicating a type of rock — quartzite is a rock made mainly of quartz.
