Why is a storm noisy? Why do trees lose their leaves in autumn? Why are there mountains? Why do we have a belly button? What are flamingos pink? Why don’t boats sink? Why is seawater salty? This book provides clear answers to many questions that children ask, but also invites them to explore further and to ask many more questions. These clear and concise answers to 150 questions about animals, the human body, and the Earth and sky are accompanied by more than 200 detailed and lifelike illustrations that help children visualize and contextualize the answers. Many of the larger illustrations are labeled, enabling children to build their vocabulary, and there is a quiz at the end of the book.
