    Written originally for those elementary school teachers who knew little of common plants and animals, and even less about earth beneath their feet and the skies overhead, this book is for the most part as valid and helpful to day as it was when first written in 1911.

    Hazen writes of how the co-evolution of the geosphere and biosphere—of rocks and living matter—has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth’s makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet’s many iterations in vivid detail. Through his theory of “co-evolution,” we learn how reactions between organic molecules and rock crystals may have generated Earth’s first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet.The Story of Earth is also the story of the pioneering men and women behind the sciences. Readers will meet black-market meteorite hawkers of the Sahara Desert, the gun-toting Feds who guarded the Apollo missions’ lunar dust, and the World War II Navy officer whose super-pressurized “bomb”—recycled from military hardware—first simulated the molten rock of Earth’s mantle. As a mentor to a new generation of scientists, Hazen introduces the intrepid young explorers whose dispatches from Earth’s harshest landscapes will revolutionize geology.
