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。
The warmer ocean would heat the air above it, which would slow the refreezing of ice in winter, which would in turn become even more susceptible to melting in summer.
温暖的海洋将加热海洋上空的空气，这将减缓冬季冰重新冻结，这反过来使海冰更加容易在夏天融化。
In 2000 he extracted deep cylinders of ice from Kilimanjaro's glaciers and found that the higher layers were full of elongated bubbles - signs that melting and refreezing had occurred in recent years.
2000年，他曾用柱体容器从乞力马扎罗山的冰川层深部提取了部分冰块，发现冰块上层充满了细长的气泡，证明在最近那几年冰层曾今融化并重新冻结。
