Quizplus · Accepted Answer

The granular substance formed by the compression of the lowest layers of snow is known as firn. Moraine refers to the accumulation of rock and sediment carried and deposited by a glacier, while till refers to the mixture of unsorted glacial sediment deposited directly by the ice. Hoar frost, on the other hand, is a type of frost formed by the sublimation of water vapor directly into ice crystals.
