The main process of ice formation is the metamorphism from melting-refreezing of the seasonally accumulated snow, therefore there exists a broad belt of superimposed ice.
冰川积累区的成冰,主要是当年积雪以融化-再冻结为主要变质成冰作用,平衡线以上附加冰带宽阔;
With further melting, refreezing, and increased weight from newer snowfall above, the snow reaches a granular recrystallized stage intermediate between flakes and ice known as firn.
随着进一步的融化、再结冰,以及上方新的降雪增加的重量,这些雪变成再次结晶阶段的颗粒状中间物,介于小薄片与冰块之间,被称作万年雪。
In the large image, the area behind the shoreline is pockmarked by marshes, ponds, and hummocks characteristic of "thermokarst," landscapes created by the melting and refreezing of permafrost.
在大图中,海岸线后面的区域由湿地、池塘、热融冰丘形成了凹陷,融化的以及重新冻结的冻土层形成了这种景观。
