The ultimate biography of the ultimate subject—planet Earth! Featuring humorous interviews, bold illustrations, cutting-edge science, and four and a half billion years of history, readers ages 10 and up will get to know the place we call home and the importance of caring for our planet well into the future! 
 
Here it is—the celebrity biography we didn’t know we wanted, and now can’t get enough of—the story of Earth, our fascinating little home in the solar system with all its crazy life forms and dramatic geological ages. Travel back through the eras, eons, and ages, and discover the major extinction events (sorry, dinosaurs!) the introduction of new species (hello, humans!), and how the land shifted and changed over time to become what we know today (Pangea who?)
 
From the chaotic Hadean eon with its huge oceans of molten rock to today’s Cenozoic era, aka the Age of Mammals, get an in-depth look at how Earth has changed in the past and how it’s changing now. Learn about the Great Oxygenation Event. Meet some of the planet’s wildest life-forms, like Megatherium—a sloth as big as an elephant—and Hallucigenia—the walking, spiky worm so named because the scientists who first discovered the fossils thought they were hallucinating. Watch the continents separate, crash together, and re-form. And catch up on the basics, like why the sky is blue and how tectonic plates create mountains, earthquakes and volcanoes. 
 
It's the ultimate biography of the best home in the galaxy for kids who are history buffs, science buffs, or just plain curious to know more about the world around them!
