The Reasons for Seasons (New & Updated Edition)

Cold 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.

Newly revised and vetted by experts, this updated edition of The Reasons for Seasons introduces the solstices, the equinoxes, and the tilt in Earth's axis that causes them, and gives examples of what each season is like across the globe from pole to pole. Clear, simple diagrams of the earth's orbit are labeled with important vocabulary, explained and reinforced with accessible explanations.

Fascinating and easy to understand, this is a perfect introduction to seasons, earth's 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.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
