Full-color photographs will draw in readers while the easy-to-read text breaks down complex concepts. A diagram of the rock cycle ties everything together and a geology-themed project provides the opportunity for hands-on experience. Other features include a table of contents, fun facts, infographics, sidebars, and an index. Aligned to Common Core Standards and correlated to state standards.
