Discover our planet--its place in space, its volcanoes, wild landscapes, deserts and oceans, hurricanes, and earthquakes. What's inside Earth, and why is it so hot under the surface? How did our planet come about, and what did it look like in the beginning? How are mountains formed and why are forests important? What happens when glaciers melt and how can we stop climate change? Explore habitats and ecosystems--inside caves, among enormous redwoods, on the savannas, or deep down under the oceans. This extraordinary encyclopedia fuels your imagination with its jaw-dropping visual approach to explain anything from what keeps Earth in its place to the great diversity of plants, animals, and people who live here, how it is changing and why it is unique. Knowledge Encyclopedia: Earth! covers everything you need to know about Earth in glorious technicolor detail alongside easy explanations and fun facts to spark young minds to find out everything about our planet and how it works.
