In this fascinating introduction to Planet Earth, large, colorful diagrams are brought to life by tiny people running around performing the actions that are explained in the text. With Earth's processes visualized in this imaginative and fun way and accompanied by bite-sized, informative text, even complex ideas are easy to understand. Readers can take an in-depth look at the workings of our planet, from the water cycle and the atmosphere, to how the seasons change and why hurricanes happen. Double gatefolds give a large space in which to explore complex processes such as the rock cycle and evolution. A follow-up to the successful book, Stuff You Need to Know About the Human Body.
