The Reasons for Seasons by Gail GibbonsCold winters, hot summers--year after year the seasons repeat themselves. But what causes them?
Why is there winter in the Southern Hemisphere at the same time there is summer in the Northern Hemisphere? In summertime, why is it still light out in the evening? With simple language appropriate for young readers, non-fiction master Gail Gibbons introduces young readers to the four seasons and explains why they change throughout the year.
Clear, simple diagrams of the earths orbit are labeled with important vocabulary, explained and reinforced with accessible explanations. The Reasons for Seasons introduces the solstices, the equinoxes, and the tilt in Earths axis that causes them, and gives examples of what each season is like across the globe from pole to pole.
Fascinating and easy to understand, this is a perfect introduction to seasons, earths orbit, and axial tilt. Different effects on different parts of the world are included, illustrating the difference in climate between the equator, the northern and southern hemispheres, and the polar regions.
What are seasons?
You probably have a favorite season. Have you ever wondered what causes the seasons, though? You probably know that the Earth spins on its axis every day, making a complete turn. In addition to this daily turning, the Earth also travels around the Sun once every year. As the Earth travels, its position in relation to the Sun changes. Sometimes, the Earth is tilting towards the Sun, which causes summer. When the Earth is tilted away from the Sun, winter comes.

Many people believe that Earth is closest to the Sun in summer and farthest in winter It is slightly elongated, so that during part of the year, Earth is closer to the Sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the Sun and summer when it is farthest away! Earth has seasons because sometime early in its long history, something very big hit the young Earth to knock it off-kilter. So instead of rotating with its axis perpendicular to its orbital plane, it is tilted
