Where would you find three-quarters of Earth's freshwater? Great Lakes, glacier ice, global rivers or ground water.
Glacier ice is the world's second largest water reservoir and it's biggest freshwater reservoir.
Glaciers cover about 10 percent of the world's total land area. And when you think of them what might come to mind are these super massive chunks of immovable ice. But some of them are anything but. Gem Glacier the smallest one in Montana's Glacier National Park covers only about five acres which is like five football fields. And the Alaska Almanac states that the state of Alaska alone is home to 100,000 glaciers. Also, they move, maybe not so fast that you can watch them drift like a boat over water. But whether glaciers are crunching downwards through valleys or spreading away from a central point, these ice masses slip, slide, creep and crawl across the surface. Scientists say most of the world's glaciers are shrinking though some are getting larger. And investigations are taking place worldwide.
冰川覆盖面积占全球土地总面积的10%左右 。提到冰川，大家可能会想到这些无法移动的超大冰块 。但有些冰块并非如此 。宝石冰川是蒙大拿州冰川国家公园中最小的冰川，其面积仅有5英亩左右，相当于5个足球场 。阿加斯加州年鉴指出，仅阿拉斯加州就有10万个冰川 。而且，冰川会移动，可能速度不是很快，但你能看到冰川像船一样在水上漂 。但无论是穿过山谷向下移动，还是从中心散开，这些冰块都在海面上滑行和蠕动 。科学家表示，全球大部分冰川都在缩小，不过也有些冰川在扩大 。目前相关调查正在世界各地进行 。
