As the glacier melts, the water carries fine material which is eventually deposited. All of the material moved by the glacial melt water is called glacial driftMaterial moved by the glacial melt water. or glacial tillIce deposited material.. glacial outwashThe sand and gravel deposited by the running melt water leaving the glacier. is the sand and gravel deposited by the running melt water leaving the glacier. The material is sortedWhen things are put into order, eg from largest to smallest.. The heavier particles of sand and gravel are deposited in the glaciated valley. The lighter, finer particles such as clay, are deposited further away from the glacier and are deposited in the outwash plainThe lighter, finer particles such as clay are deposited a long distance from the glacier in the outwash plain..
