Glacier. A large, slow-moving mass of compacted ice formed from accumulated snowfall over thousands of years, found in polar regions and high mountain areas.

A sino-Japanese compound describing a river-like body of ice. Glaciers shape landscapes through erosion, carving U-shaped valleys and fjords. In contemporary usage, 氷河 frequently appears in climate-change discussions as glacial retreat is a key indicator of global warming. The compound 氷河期 (ice age) is also commonly used in both scientific and colloquial speech.
