"Each morning, the sun rises in the east. Each night, the sun sets in the west. You might think the sun orbits Earth. However, Earth actually orbits the sun. The sun looks like it's moving because of the rotation of Earth on its axis. This book helps readers to discover why the sun sets each night. . . Readers will be able to visualize how Earth's position relative to the sun affects whether it's day or night"--Provided by publisher.
