1.Glaciers are extended, moving streams and plains of ice that have endured year after year. 由於冰河的扩张，流动的溪流和冰原已经……. 2.They are formed by snow falling, collecting over time, and compacting into what is called “neve.” 冰原是由雪崩、多时的堆积跟长年的紧实形成的。 3.Neve is the grainy, outer layer of the upper end of a glacier that has survived one or more melting seasons. The great accumulation of neve changes into large ice crystals that become several centimeters in size, making it very dense and slightly blue in color 冰原是颗粒状的，顶端的外层冰河已经….. 冰原的大量堆积会形成好几公尺高的冰晶， 看起来是非常紧密且会呈现浅蓝色。 4.Glaciers lose snow from erosion, thawing, evaporation, and “calving,” which is a separation from a large ice mass due to breakage. The two main types of glaciers are continental glaciers, or “ice sheets,” and valley glaciers. 冰河的雪容易溶化，溶解，蒸发，还有崩解。崩解的原因是冰的大量分离，这两种形态的 冰河就是大陆冰河或是冰床或是狭谷冰河。 5.A glacier’s sheer mass is set into motion by gravitational pull. They move very slowly down valleys, mountains, and over extensive areas, as in Antarctica. 冰河的…… 是由引力的拉力置入的。 南极洲的冰河、冰谷、冰山移动非常缓慢且蔓延 了极大的区域。 6.They are normally found in high latitudes and altitudes, because they usually gain more snow in the winter than they lose in the summer. 冰山通常都是在高纬度高海拔的地方发现的，因为冰山在冬天时堆积更多雪比在夏天时流 失的雪还要多。 7.Although most of the glaciers in the world are located at the poles, they are found on every continent, except Australia. 虽然世界上大部份的冰河都位於两极，冰河还是在存在於每块大陆，除了澳大利亚 对自己翻的没信心，请求神人帮忙!! --
