Glaciers are slowly moving masses of ice that have accumulated on land in areas where more snowfalls during a year than melts.

冰川正在缓慢地移动大量的冰，这些冰是在每年降雪量大于融化量的地区，在陆地上累积起来的。

Last time, we started to talk about glaciers and how these masses of ice form from crystallized snow, and some of you were amazed at how huge some of these glaciers are.

上次我们开始讨论了冰川以及这些大型冰块是如何从结晶雪中形成的，你们中的一些人对这些冰川的巨大感到惊讶。

Glaciers may form in permanently cold areas, and these slowly moving masses of ice cut out valleys, carrying with them huge quantities of eroded rock debris.

冰川可能形成于长期寒冷的地区，而这些缓慢移动的冰块切割了山谷，带走了大量被侵蚀的岩石碎片。

The 750 or so icebergs that break off from glaciers each year and drift south from Greenland are floating masses of freshwater ice formed in the pristine air of 5, 000 years ago.

"Those water masses play a very important role in the present-day status of the ice pack and changes in the delivery would have an influence and effect on ice distribution, " said Weingartner.
