Describes the Great Global Rift that runs beneath the Atlantic Ocean, how it was discovered, and its effect on weather, tides, and the physical shape of the earth.
A collection of essays and articles provides a study of how the planet works, discussing Earth's structure, geographical features, geologic history, and evolution.
The Great Rift Valley, which runs some three thousand miles from Syria to Mozambique, is one of the earth's most extraordinary geological features. The result of Syria's split from the African continent fifteen million years ago, this great "crack in the earth" crosses Jordan, Syria, Israel, Tanzania, Ethiopia, and Kenya. In 2004, Israeli journalist Haim Watzman set out to explore the northern part of the Rift Valley, where he had lived for nearly two and a half decades. He interviewed a number of scientific experts: a zoologist fascinated by the behavioral patterns of indigenous birds; an archaeologist trying to re-create the standing stone formations left to us by ancient cultures; a geologist speculating on the valley's origins. Watzman raises provocative questions about the nature of this massive feature in the earth's crust: where it comes from, how it has developed, and how human civilization has fared on its shores. "Humankind has overlaid the geology not just with cities, dams, fields, and roads," he writes, "but also with history and biography and meanings."
The Great Rift is a sweeping history of the intertwined careers of Dick Cheney and Colin Powell, whose rivalry and conflicting views of U.S. national security color our political debate to this day. Dick Cheney and Colin Powell emerged on the national scene more than thirty years ago, and it is easy to forget that they were once allies. The two men collaborated closely in the successful American wars in Panama and Iraq during the presidency of George H. W. Bush--but from this pinnacle, conflicts of ideology and sensibility drove them apart. Returning to government service under George W. Bush in 2001, they (and their respective allies within the administration) fell into ever-deepening antagonism over the role America should play in a world marked by terrorism and other nontraditional threats. In a wide-ranging, deeply researched, and dramatic narrative, James Mann explores each man’s biography and philosophical predispositions to show how and why this deep and permanent rupture occurred. Through dozens of original interviews and surprising revelations from presidential archives, he brings to life the very human story of how this influential friendship turned so sour and how the enmity of these two powerful men colored the way America acts in the world.
The flora and fauna of one of Africa's most spectacular regions is documented in 202 photographs, from snow-topped mountains to heat-blasted salt flats.
Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.
