Ch?tairiku: Hyakuokunen No Chiky?shi

To understand continental drift and plate tectonics, the shifting and collisions that make and unmake continents, requires a long view. The Earth, after all, is 4.6 billion years old. This book extends our vision to take in the greatest geological cycle of all--one so vast that our species will probably be extinct long before the current one ends in about 250 million years. And yet this cycle, the grandest pattern in Nature, may well be the fundamental reason our species--or any complex life at all--exists.
