答案 Glaciers冰川
    Glaciers are formed in places where the temperatures are extremely cold. / This could even include places that are at sea level, / but are mostly places that are high up on mountains. / In such cold places it snows most of the year. / This snow will settle down and when it snows again / the lower layer of snow gets compressed. / Every time it snows, the below layers will compress more, / finally turning into hard ice. / This ice is what forms the glacier. / When the temperature rises slightly, / the outer edges of the formed glacier and fresh snow will melt. / For a glacier to form and sustain itself it is of prime importance / that the amount of snow that falls on it must be more than the amount of glacier that has melted. / This is the only way in which the glacier will be able to maintain itself / and keep increasing in size year after year. /
