我剛才登上的巨大冰柱,是由水凍成的
it formed this year, whereas that glacial ice upthere,
是近期形成的,而在那邊的冰川
formed over thousands of years in a completely different way.
數(shù)千年前就以另一種方式形成了
Glaciers are not formed from frozen water.
冰川并不是由凍水形成的
They are made from snow.
它們由雪變來
Every snowflake is formed from dozens of delicate ice crystals.
每一片雪花由幾十個精巧的冰晶組成
No one has ever found two that are the same.
每人能發(fā)現(xiàn)有兩片一樣的
Individual snowflakes may be fragile
單獨的雪花可能是脆弱的
but put enough together and they create one of the most awe-inspiring sights in nature.
但是聚合起來它們能創(chuàng)造 一個自然界中令人敬畏的景象
Every year, around a million avalanches thunder down the Earth's mountains.
每一年,地球上的山峰有百萬計的雪崩
But however devastating avalanches may appear to us,
盡管破壞性的雪崩威脅我們的安全
when it comes to reshaping the Earth, they barely even scratch the surface.
但是對于重塑世界,它甚至不能破壞地球表面
When snow turns into ice,
只有當雪變成冰
it becomes so powerful it can change our world.
才具有改變世界的力量
