However, at intervals of 10 to 100 years, these glaciers move forward

2、up to 100 times faster than usual. The surge often progresses along a glacier like a great wave, proceeding from one section to another. Subglacial streams of meltwater might act as a lubricant, allowing the glacier to flow rapidly toward the sea. The increasing water pressure under the glacier migh

3、t lift it off its bed, overcoming the friction between ice and rock, thus freeing the glacier, which rapidly sliders downhill. Surge glaciers also might be influenced by the climate, volcanic heat, or earthquakes. However, many of these glaciers exist in the same area as normal glaciers, often almos

4、t side by side. Some 800 years ago, Alaska's Hubbard Glacier advanced toward the sea, retreated, and advanced again 500 years later. Since 1895, this seventy-mile-long river of ice has been flowing steadily toward the Gulf of Alaska at a rate of approximately 200 feet per year. In June 1986, how

5、ever, the glacier surged ahead as much as 47 feet a day. Meanwhile, a western tributary, called Valerie Glacier, advanced up to 112 feet a day. Hubbard's surge closed off Russell Fiord with a formidable ice dam, some 2,500 feet wide and up to 800 feet high, whose caged waters threatened the town

6、 of Yakutat to the south. About 20 similar glaciers around the Gulf of Alaska are heading toward the sea. If enough surge glaciers reach the ocean and raise sea levels, west Antarctic ice shelves could rise off the seafloor and become adrift. A flood of ice would then surge into the Southern Sea. Wi

7、th the continued rise in sea level, more ice would plunge into the ocean, causing sea levels to rise even higher, which in turn would release more ice and set in motion a vicious cycle. The additional sea ice floating toward the tropics would increase Earth's albedo and lower global temperatures

8、, perhaps enough to initiate a new ice age. This situation appears to have occurred at the end of the last warm interglacial (the time between glacations), called the Sangamon, when sea ice cooled the ocean dramatically, spawning the beginning of the Ice Age. 想要史上最全的 托福閱讀 真題嗎?趕快來下載 小馬 app機(jī)經(jīng)庫吧，包含了史上最
