Rocks, Rivers and the Changing Earth

Your bones and your teeth originated at the bottom of the sea, and the color of your blood came from deep underground. The water you drink, the clothes you wear, and the house you live in are all part of the Earth's history. With this well-illustrated book, you'll discover fascinating facts about geology, from how powerful prehistoric forces formed a river bend to the ways that tiny pebbles can reflect a million years of history. Your adventure begins with evidence that's all around you and can make even an ordinary walk in the park into an exciting revelation. Other subjects range further afield, from rivers of ice and volcanic activity to the formation of precious stones. In addition, a series of fascinating experiments provide you with insights into some of the geologic events that constantly transform our planet.
