About
Rocks and soil; they're always underfoot. They're also in space, inside Earth, and in volcanoes. In this book, readers will discover how rocks, soil, and minerals are formed, and what they're made of. Activities and questions expand on topics introduced in the text, and stimulate readers to think critically about rocks and soil. Readers will develop the skills to question and experiment scientifically, and the vocabulary to record and discuss their observations.
