moraine
含义: An accumulation of rocks, soil, and debris deposited by a glacier, forming ridges and mounds that mark the glacier's former extent.
Moraines are key evidence used by geologists to reconstruct the history of glaciation. Different types include terminal moraines (marking the furthest advance of a glacier), lateral moraines (along the sides), and medial moraines (formed where two glaciers merge). In Britain, moraines are particularly visible in the Scottish Highlands, the Lake District, and Snowdonia, providing evidence of past ice ages.
例句
