2、y they admire has just caused a staggering loss of life. Even so, scientists argue that in the very long view, the global process behind great earthquakes is quite advantageous for life on earth especially human life.Powerful tremors (震动) like the one that sent killer waves racing across the Indian
3、Ocean on Dec. 26 (2004) are inevitable side effects of the constant recycling of planetary crust, which produces a cozy, habitable planet. Some experts refer to the regular blows hundreds a day as the planets heartbeat.The advantages began billions of years ago, when this crustal recycling made the
4、oceans and atmosphere and formed the continents. Today, it builds mountains, enriches soils, regulates the p Janets temperature, concentrates gold and other rare metals and maintains the seas chemical balance.Plate tectonics (after the Greek word “tekton“, or builder) describes the geology. The trag
5、ic downside is that waves of quakes and volcanic eruptions along plate boundaries can devastate human populations. “Its hard to find something uplifting about 150,000 lives being lost,“ said Dr. Donald J. DePaolo, a biologist at the University of California, Berkeley. “But the type of geological pro
6、cess that caused the earthquake and the tsunami is an essential characteristic of the earth. As far as we know, it doesnt occur on any other planetary body and has something very directly to do with the fact that the earth is a habitable planet.“Many biologists believe that the process may have even
7、 given birth to life itself. The main benefits of plate tectonics accumulate slowly and globally over the ages. In contrast, its local upheavals can produce regional catastrophes, as the recent Indian Ocean quake made clear. Even so, scientists say, the Dec.26 (2004) tsunamis may prove to be an ecol
8、ogical boon (裨益) over the decades for coastal areas hardest hit by the giant waves.Dr. Jelle Zeilinga de Boer, a geologist at Wesleyan University who grew up in Indonesia and has studied the islands, says historical evidence from earlier tsunamis suggests that the huge waves can distribute rich sedi
9、ments from river systems across coastal plains, making the soil richer. “It brings fertile soils into the lowlands,“ he said. “In time, a more fertile jungle will develop.“Dr. de Boer, author of recent books on earthquakes and volcanoes in human history, added that great suffering from tectonic viol
10、ence was usually followed by great benefits as well. “Nature is reborn with these kinds of terrible events,“ he said. “There are a lot of positive aspects even when we dont see them.“Plate tectonics holds that the earths surface is made up of a dozen or so big crustal slabs (板块) that float on a sea
11、of melted rock. Over ages, this churning (翻腾的) sea moves the plates as well as their continents and ocean basins, tearing them apart and rearranging them like pieces of a puzzle.The process starts as volcanoes burst forth hot rock that spreads out across the seabed. Eventually, hundreds or thousands
12、 of miles away, the cooling slab collides with other plates and sinks beneath them, plunging back into the hot earth. The colliding plates grind past one another about as fast as fingernails grow and over time produce mountains and swarms of earthquakes as frictional stresses build and release. Mean
13、while, parts of the descending plate melt and rise to form volcanoes on land.The recent cataclysm (地震) began in a similar manner as volcanic gashes (裂缝) in the western depths of the Indian Ocean ejected molten rock to form the India plate. Its collision with the Burma plate created the volcanoes of
14、Sumatra as well thousands of earthquakes, including the magnitude 9.0 killer.But despite such staggering losses of life, said Robert S. Derrick Jr., a geophysicist at the Woods Hole Oceanographic Institution, “Theres no question that plate tectonics rejuvenates (更新) the planet.“ Moreover, geologists
15、 say, it demonstrates the earths uniqueness. In the decades after the discovery of plate tectonics, space probes among the 70 or so planets and moons that make up the solar system found that the process existed only on earth as revealed by its unique mountain ranges.In the book “Rare Earth“ (Coperni
16、cus, 2000), which explored the likelihood that advanced civilizations dot the cosmos, Dr. Peter D Ward and Dr. Donald Brownlee of the University of Washington argued in a long chapter on plate tectonics that the slow recycling of planetary crust was uncommon in the universe yet essential for the evo
17、lution of complex life. “It maintains not just habitability but high habitability,“ said Dr. Ward, a paleontologist (古生物学者). (Dr. Brownlee is an astronomer.) Most geologists believe that the process yielded the earths primordial (原始的) ocean and atmosphere, as volcanoes spewed (喷涌) vast amounts of wa
18、ter vapor, nitrogen, carbon dioxide and other gases. Plants eventually added oxygen. Meanwhile, many biologists say, the earths first organisms probably arose in the deep sea, along the volcanic gashes.“On balance, its possible that life on earth would not have originated without plate tectonics, or
19、 the atmosphere, or the oceans,“ said Dr. Frank Press, the lead author of “Understanding Earth“ (Freeman, 2004) and a past president of the National Academy of Sciences. The volcanoes of the recycling process make rich soil ideal for producing coffee, sugar, rubber, coconuts, palm oil, tobacco, pepp
20、er, tea and cocoa. Water streaming through gashing in the seabed concentrates copper, silver, gold and other metals into rich deposits that are often mined after plate tectonics pushes them onto dry land.Experts say the world ocean passes through the rocky pores of the tectonic system once every mil
21、lion years or so, increasing nutrients in the biosphere and regulating a host of elements and compounds, including boron (硼) and calcium.Dr. William H. Schlesinger, dean of the Nicholas School of the Environment and Earth Sciences at Duke, says one vital cycle keeps adequate amounts of carbon dioxid
22、e in the atmosphere. Though carbon dioxide is thought to cause excessive greenhouse gas warming of the planet, an appreciable level is needed to keep planet warm enough to support life. “Having plate tectonics complete the cycle is absolutely essential to maintaining stable climate conditions on ear
23、th,“ Dr. Schlesinger said. “Otherwise, all the carbon dioxide would disappear and the planet would turn into a frozen ball.“Dr. Press, who was President Jimmy Carters science adviser, said the challenge in the coming decades would be to keep enjoying the benefits of plate tectonics while improving o
24、ur ability to control its deadly byproducts. “Were making progress,“ Dr. Press said. “We can predict volcanic explosions and erect warning systems for tsunamis. Were beginning to limit the downside effects./（分数：49.00）(1).Scientists believe that the crustal recycling process _.（分数：7.00）A.produces mor
