Join the savvy, accident prone Stickmen as they uncover each slice through the Earth to show what happens, and what exists, at all levels - everywhere: through layers of the atmosphere that wrap around the globe; from mountain tops and live volcanoes down to the molten core: from the ocean's sunlight zone to the deepest trench in the seabed and from the rooftop of the tallest skyscraper to the foundations of a city and its maze of underground tunnels. Discover: * why aircraft ride the jet streams to improve their speed * what makes a volcano explode * the underground systems that keep cities running * the creatures that live in the deepest parts of the oceans . and much more. Clear, cut-away illustrations and diagrams reveal mechanisms at work, with the Stickmen always on hand to share facts (and jokes), explain functions - and even help to load baggage onto a plane!.
