地球的力量 第3集 冰川(4)雪變成冰

On this ice cliff you can actually see

在這個(gè)冰崖，你能清晰看到

the transformation of snow into ice as it happens.

雪變成冰的過(guò)程

Each year's snowfall creates distinct layers manyfeet deep.

每年的降雪都造成明顯的雪層，許多數(shù)米厚

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

現(xiàn)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.

接下來(lái)，看這些褐色線，是夏天前融化的

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

所以你越深入觀察這些雪層，雪堆積的時(shí)間越久遠(yuǎn)

It's kind of like the rings of a tree

就像樹的年輪

with each layer being a new layer of snowfall,

老雪層被新雪層套著

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

所有這些雪崩的重量

that starts to compress the individual snowflakes together.

是由獨(dú)立的雪花壓縮而成的

The further down the layers you go,

越往下接觸的雪層就

the harder the snow becomes until you reach here.

越硬，到了這里

This is a really distinctive set of snow.

這是很特別的雪

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

叫做粒雪，數(shù)年前形成

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

這真的很硬，我用冰鎬挖它

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

這是神奇的聚集物就像氣泡玻璃纖維

It's beautiful.

真漂亮
