Learn all about rocks and minerals and how we study them. Almost all rocks are made of minerals. Learn about the three different types of rocks: igneous rocks, sedimentary rocks, and metamorphic rocks. A rock can even transform over millions of years from one type of rock to another during the rock cycle. Easy-to-read text paired with vibrant images keep students engaged from cover to cover. This reader also includes instructions for an engaging science activity where students can see how crystals form. A helpful glossary and index are also included for additional support.
