Metamorphic rocks are a great example of change; they start out as another kind of rock, but change dramatically under high pressure, heat, or another natural force. This book introduces readers to this fascinating part of the rock cycle, using bright color photographs and accessible hi-lo text. Readers will learn about common metamorphic rocks such as schist and marble, including how they were made and how they're used. Graphic organizers and fact boxes showcase exciting information about this kind of rock. Readers will come to appreciate why metamorphic rocks... rock!
