Did you know that there is a bus-sized potassium crystal feldspar in Russia? Or that most of the gold, silver, and platinum found at the Earth's surface is thought to have arrived on meteorites from outer space? Understanding how rocks form helps us to see how the Earth and the solar system work, how the planet has changed over millions of years, and how it might look in the future. Complete with fascinating side notes, an illustrated explanation of the rock cycle, a timeline, and a glossary, this guide to geology for readers 9 and up also features Anna Alanko's skillful collages of a wide array of stones, gems, and fossils, as well as such sites as volcanic Kilauea, Giant's Causeway, and Antarctica's Mount Erebus.
