Detailed explanation-1: -Moraines consist of loose sediment and rock debris deposited by glacier ice, known as till. They may also contain slope, fluvial, lake and marine sediments if such material is present at the glacier margin, where it may be incorporated into glacial ice during a glacier advance, or deformed by glacier movement4, 5.
Detailed explanation-2: -Encyclopedic entry. A moraine is material left behind by a moving glacier. This material is usually soil and rock.
Detailed explanation-3: -Moraines are landforms composed of glacial till deposited primarily by glacial ice. Glacial till, in turn, is unstratified and unsorted debris ranging in size from silt-sized glacial flour to large boulders. The individual rock fragments are typically sub-angular to rounded in shape.
Detailed explanation-4: -The sediments deposited by glacial meltwater are called outwash. Since they have been transported by running water, the outwash deposits are braided, sorted, and layered. The broad front of outwash associated with an ice sheet is called an outwash plain; if it is from an alpine glacier it is called a valley train.
