There's more than just dirt below! Readers will learn about the layers and types of soil underground. Rocks, clay, sand, silt and all nonliving things underground are explored. Earth's core, mantle, and crust are also discussed. Readers will also discover why we could not live without dirt, and why we need to protect it.
