Driving through the northeastern part of the United States during the fall is much different than traveling through the Southwest. Vermont will have many trees with their leaves changing color, while a state like Arizona will be dry, hot, and not have much vegetation. These states are in different climate zones! Readers learn the main features of Earth’s climate zones, including the tropical, temperate, polar, Mediterranean, highland, and arid zones. Full-color photographs and maps of these regions aid the main content in supporting both science and geography curricula.
