Travel from the peaks of the tallest mountains to the depths of the lowest valleys to discover what each layer contains. Learn how people live in various environments and altitudes on Earth.
Splash with the Stickmen at the sea's surface, and then dive down through the darkening zones and into the abyss. But don't stop there! Follow the Stickmen to snorkel around coral gardens, find creatures that make their own light, and dive 7 miles down to the deepest trench. The Stickmen have plenty of oxygen (and wild facts) to keep you alert as you float past coral gardens, pods of humpback whales, robotic submarines, and the weirdest creatures of the deep.
Earth's atmospheric layers include the exosphere, thermosphere, mesosphere, stratosphere, and troposphere. How and why have scientists divided Earth's atmosphere into these layers? What exactly are these layers made up of? What happens in each layer? Readers will learn the answers to these questions and more in this enriching text that supports curricular science studies. Readers will identify the various traits of each of the atmospheric layers, ascertain their functions, and appreciate their significance in regulating conditions on Earth.
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.
