The Ultimate Book of Planet Earth offers lots of opportunity for hands-on interaction using flaps, pop-ups, and more! Pull a tab to see how magma erupts from a volcano, turn a page for a pop-up of a mountain range, or rotate a wheel to move the blades of a wind turbine! Planet Earth explores not only the geology of the Earth—oceans, continents, and the formation of mountains and volcanoes—but also its geo graphy, atmosphere, and weather. A valuable reference book for any child!
