Why Is Earth Round?

by Patricia J. Murphy

This book not only answers this compelling question, it explains why people once thought Earth was flat, what Earth is made of, the cause of Earth's seasons, and how Earth moves around in space. With gravity, the Sun, and specially designed diagrams as tour guides, students can get comfortable with the unique features of our planet.
