地球的力量 第3集 冰川(4)雪变成冰

On this ice cliff you can actually see

在这个冰崖，你能清晰看到

the transformation of snow into ice as it happens.

雪变成冰的过程

Each year's snowfall creates distinct layers manyfeet deep.

每年的降雪都造成明显的雪层，许多数米厚

Now, above me is the fresh snow from this winter,

现在，在我上方是今年新下的雪

and down here, this brown line is the melt from the summer before.

接下来，看这些褐色线，是夏天前融化的

So as you go down through these layers, the snow gets older and older.

所以你越深入观察这些雪层，雪堆积的时间越久远

It's kind of like the rings of a tree

就像树的年轮

with each layer being a new layer of snowfall,

老雪层被新雪层套着

and it's the weight of all those snowfalls building up

所有这些雪崩的重量

that starts to compress the individual snowflakes together.

是由独立的雪花压缩而成的

The further down the layers you go,

越往下接触的雪层就

the harder the snow becomes until you reach here.

越硬，到了这里

This is a really distinctive set of snow.

这是很特别的雪

It's called neve and it formed several years ago.

叫做粒雪，数年前形成

It's really hard, I mean, I have to dig at it with my ice axe.

这真的很硬，我用冰镐挖它

It's amazing stuff. It's kind of Like a bubbly fibreglass.

这是神奇的聚集物就像气泡玻璃纤维

It's beautiful.

真漂亮
