Have you ever thought about what the world would be like without mountains? Mountains aren't just a fun place to visit - they change the weather patterns and long-term climate, and even affect how species evolve. This book tells the story of how mountains grow and erode, how the oldest species on Earth relies on mountains, and how the rise of the Himalaya may have cooled Earth's climate.

All of this is real science, written at a level that kids can read and understand. The text is supplemented with interesting illustrations and photographs to make the science more vivid, appropriate for both standard Kindle and tablet formats. At the end of the book you will find a self-quiz to test your new knowledge, additional activities that build on the science, and a glossary for the scientific terms used in the book.
