e. Moraine
Moraine is a French word that refers to any glacially formed accumulation of unconsolidated debris. This debris may be plucked off the valley floor as a glacier advances or fallen off the valley walls as a result of frost wedging. Moraine may be comprised of silt like glacial flour to large boulders. The debris is typically angular. Moraine may be on the glacier’s surface or deposited as piles or sheets of debris where the glacier has melted. Moraine may also occur when rocks fall in the sea.
