Have you ever been asked by a child what's underneath the ground--particularly when they see workers digging up a street? Well, if you've ever been stumped by the ensuing questions, this is the book for you. Guillain and Zommer don't just explain (and wonderfully illustrate) the subterranean water pipes and cables beneath our towns and cities--they go down, layer by layer, all the way to the center of Earth and back out the other side! Children will love the visual layout and creative text features, not to mention the accordion format of the book, which continuously folds out way past the tallest member of your family. A great book for those children who meet each answer given them with another question. Find it here in the Library!
