This book is an expository writing purposely written for readers to take information away from the text. It goes through a variety of things on our planet earth such as mountains, rivers, deserts, caves, oceans and even including space. The illustrations are placed in the middle of the page with small excerpts all around it. This book could great use at the lower elementary level with the pictures, easy to read text, and could be a positive example of how books use table of contents because children at that age are just learning how books and there parts work.
