This lavishly illustrated book is a fun first reference for inquisitive young children who want to know more about their world. Twenty-two richly detailed panoramic spreads transport readers to some of the most fascinating places on earth, along the way highlighting animals, plants, elements, and environments. Over 100 animals and plants are here, shown in their native habitats from North American forests and African savannas to Arctic tundra and tropical coral reefs. Special introductory sections explain how living things grow and show the major animal and plant families. "Up Close" pages reveal secrets of such familiar things as air, trees, water, and grass. Featured facts cover such child-friendly subjects as animal camouflage and how rivers form, while a glossary helps parents and teachers answer young readers' questions.
