Layer by layer, it reveals the hidden world beneath our feet, from animal burrows and tangled roots to city pipes, subway tunnels, and ancient fossils. It nurtures a sense of wonder and rewards a child's inquisitiveness with clear, simple explanations and engaging illustrations. For a budding scientist or any kid who loves the outdoors, this book turns a simple question into a fascinating exploration of the natural and man-made systems underground.
None applicable. This is a straightforward, secular science and nature book.
A curious 4- to 7-year-old who is in their "why" phase. Specifically, a child who loves playing outside, digging in sand or dirt, and is starting to ask questions about how the world works. It's perfect for a pre-K or early elementary student showing an early interest in science, nature, and engineering.
No preparation is needed. The text is simple, and the concepts are clearly illustrated. A parent can read it cold and learn alongside their child. The illustrations are bright and engaging, with nothing that would be considered scary. The child has just started digging a hole in the backyard "to see what's down there," or repeatedly asks what's under the sidewalk, the street, or their house. The parent wants a book that answers this question in a fun, visual, and educational way.

Sign in to write a reviewA younger child (4-5) will be captivated by the cutaway illustrations of animals in their homes and the simple idea of a hidden world. An older child (6-8) will absorb more of the specific scientific concepts, like the different types of soil, the function of roots, the existence of fossils, and the basic layers of the Earth. The book can serve as a vocabulary builder and a jumping-off point for more detailed questions for this older group.
While many books explore animal burrows, this book's strength is its comprehensive, multi-layered approach. It uniquely integrates the natural world (animals, roots), the human-built world (pipes, subways), and the geological world (fossils, core) into a single, cohesive visual explanation. The cutaway illustrations across spreads make the abstract concept of "underground" incredibly concrete and accessible for young children.
This nonfiction book presents a top-to-bottom exploration of the world underground. It begins at the surface with grass and insects, then moves deeper to reveal layers of soil, animal burrows (moles, ants, rabbits), and plant root systems. The scope expands to include human-made structures like pipes and subways, then delves into geological history with fossils and caves, before concluding with the Earth's core.
