From the acclaimed author of The Last Volcano and Earthquake Storms comes the incredible story of the creation of a continet.
For most of modern history, geologists could say little more about why mountains grew than the obvious: There were forces acting inside the Earth that caused mountains to rise. But what were those forces? And why did they act in some places of the planet and not at others?
When the theory of plate tectonics was proposed, our concept of how the Earth worked experienced a momentous shift. As the Andes continue to rise, the Atlantic ocean slowly widens, and Honolulu creeps ever-closer to Tokyo, this seemingly impercepitable creep of the Earth is revealed in the landscape all around us.
But tectonics cannot – and do not – explain everything about the wonders of the North American landscape. What about the Black Hills? Or the walls of chalk that stand amongs the rolling hills of west Kansas?
The states of Washington and Oregon are slowly rotating clockwise, and there a diamond mine in Arizona – and it all points to the geologic secrets hidden inside the 2 billion year-old-continental masses,. A whopping ten times older than the rocky floors of the ocean, continents hold the clues to the long history of our planet.
With a sprightly narrative that brings science to vivid life, John Dvorak's How the Mountains Grew will fill readers with a newfound appreciation for the ground beneath their feet.
