Three kinds -- The rock cycle -- Picture glossary -- Index -- To learn more.
Summary:
"In Rocks, beginning readers are introduced to the rock cycle, how sedimentary, metamorphic, and igneous rocks form, where we can find them on Earth, and how people use them in everyday life. Vibrant, full-color photos and carefully leveled text engage beginning readers as they learn how rocks form and change. A picture diagram shows the rock cycle, while a picture glossary reinforces new vocabulary. Children can learn more about rocks online using our safe search engine that provides relevant, age-appropriate websites. Rocks also features reading tips for teachers and parents, a table of contents, and an index. Rocks is part of Jump!'s Earth Basics series"-- Provided by publisher.
