Answer Choices
○Glaciers, which atpresent contain 80 percent of Earth's freshwater, form when accumulated snow iscompressed and recrystallized into ice over a period of years. ○When there are glacierson Earth, water is cycled through the glacier system, but the cycle period maybe hundreds of thousands of years during periods of ice ages. ○The glacial systemis governed by precipitation and temperature in such a way that glaciers cannotform in temperate latitudes. ○When glacial icereaches adepth of 30 meters, the weight of the ice causes ice crystals at the bottom toflow, and the resulting movement of the glacier carves the landscape. ○Ifglobal warming melted the world's glaciers, sea level would rise about 60meters worldwide. ○Glaciers have hadlittle effect on Earth's surface because only 2 percent of Earth's water iscurrently contained in glaciers, and there are fewer glaciers now than at mosttimes in the past. 【第五个选项为什么错?】 |
