... When land that is originally flat is covered by a glacier, a gently undulating topography is formed, strongly influenced by geological structures. Due to the damming of sedimentary landforms such as drumlins, eskers (from the Irish word eiscir), and moraines, lakes and marshes can form, as in the area around Hudson Bay (Canada). Mountains that rose above the surface of the glacier during the Ice Age have a gently sloping topography due to glacial erosion at the base, but a rugged topography at the peak. *Some of the terminology that mentions "drumlin" is listed below.

… もともと起伏が小さい土地が氷河に覆われると,地質構造の影響を強く受けたなだらかな波状の地形が形成される。ドラムリンdrumlin,エスカーesker(アイルランド語eiscirに由来),モレーンなどの堆積地形によるせき止めもあって,ハドソン湾周辺(カナダ)のように湖沼地帯になることがある。氷河時代に氷河の表面より上にそびえていた山地は,山麓部が氷食を受けてなだらかな地形となっているのに,山頂部はごつごつした地形となる。… ※「drumlin」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
