Why seasons change

"In some parts of the world, Earth's four seasons are very different-but some places don't experience much of a change in seasons at all. This book explains the science behind the changing of the seasons. The features of each season are explained in the context of the Earth's position relative to the sun. Age-appropriate text, full-color photographs, and infographics demystify this complex topic. Readers will learn more about our yearly journey around the sun"--Provided by publisher.
