a time in the past when the temperature was very cold and glaciers covered large parts of the earth

any period of time during which a large part of the earth's surface was covered with ice, due to the advance of glaciers, as in the late Carboniferous period, and during most of the Pleistocene glaciation

冰期
In this region, because there is abundant precipitation for glacier development, glaciers are sensitive to temperature changes. Consequently, glacial extent changes most dramatically during the alternation of glacial and interglacial periods, such as the last glacial period.
是我國(guó)海洋性冰川發(fā)育的主要地區(qū)之一，其在水分周轉(zhuǎn)中周期短，強(qiáng)度大，變化幅度也較大，對(duì)氣候波動(dòng)的響應(yīng)敏感，因此在冰期—間冰期鏇廻中雪線(xiàn)就會(huì)出現(xiàn)大範(fàn)圍的波動(dòng)。
