How to Dig a Hole to the Other Side of the World by Faith McNulty, illustrated by Marc Simont
I can't remember where I saw this book mentioned, but I requested it from inter-library loan because I thought it might go well with our study of mountains and volcanoes next year. It's perfect!
This book is a fascinating tour of the inside of the earth, all the layers you'd find if you were to dig a hole from North American straight through the center of the earth. It's silly enough to make children laugh, but full of facts and terminology, not to mention some sharks (which are always welcomed by First Son and First Daughter). The illustrations are wonderful, too.
