Rex and the Crater of Doom","description":"\u003cp\u003eSixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished.\u003c\/p\u003e\u003cp\u003eThis horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.\u003c\/p\u003e-- \"Kirkus Review\"\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Princeton University Press\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/15\/2015\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780691169668\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 208\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.48lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.40h x 5.40w x 0.70d\u003cbr\u003e\u003cb\u003eAccelerated Reader Quiz #\/Name: \u003c\/b\u003e66998 \/ T.
