Question: How do glaciers acquire their load of sediment? Need Assignment Help? Sediments and rocks fall off the cliffs surrounding the glacier and move through crevasses to the base of the glacier. Sediments and rocks form on top of the glaciers through lithification. Sediments and rocks are deposited on glaciers by streams that flow into the glaciers. Sediments and rocks are plucked off the ground surface at the base and sides of the glacier. All of the answers describe major contributors to the glacial load.
