Almost 14.5 billion years ago, it all started with a Big Bang and what began as a cloud of gas, dust, and rock eventually took shape and bloomed into a molten sphere. Battered by asteroid collisions, ice ages, and shifting tectonic plates, our fledgling planet finally pushed forth continents. But if you think Earth has calmed down since then—think again! Geological activity such as earthquakes, volcanoes, and tsunamis continues to sculpt the earth’s landscape, sometimes with terrible consequences for its inhabitants.   In this one-of-a-kind, wild, but true history of Earth, two-time Sibert Honor Medalist Don Brown takes on big concepts with humor and ease.
