When rocks change because of environmental conditions, the new rocks are called metamorphic rocks. A rock's chemical or physical makeup may change because of conditions such as temperature, stress, or pressure. In this book, readers will learn where metamorphic rocks are most commonly found, the different types of metamorphism, how metamorphic rocks are identified, and more. Color photographs depict these rocks in nature, and a
graphic organizer shows how these rocks form.
