A Tunnel Under Our Feet - Hardcover

by Sheila Yazdani (Author)

A Tunnel Under Our Feet introduces young readers to tunnels -- how they are bored through rock and soil, lined for safety, and used for water, power, travel, and mining. Children discover the machines and methods that make tunnels possible and the many ways they connect our world. Classroom-ready with comprehension support, a glossary, and index.
