A fun, eye-opening book of answers to the eternal question "Why?" across a range of exciting topics.

Why is the sky blue? How is a volcano formed? When will I stop growing? Why did the dinosaurs go extinct? How much water is in a single droplet? What's inside a camel's hump? Where do storks fly to? When was the first computer made? All these questions and more—whimsical, profound, original, but never less than serious, and asked by actual children—are taken from the website Images doc, where science reporters answer them every month. With help from specialists and experts, the authors simply and generously tackle these fascinating queries, helping children to understand why the world is the way it is.
