HOW DO GLACIERS ERODE ROCK?AS THEY FLOW ACROSS A LANDSCAPE GLACIERS PICK UP EVERYTHING IN THEIR PATH, FROM SAND GRAINS TO GIANT BOULDERS.
These rocks and sediment get frozen into the bottom of the glacier and carried along with it as it moves. The rocks stuck in the bottom of the glacier get dragged over the bedrock by the forward motion of the glacier.
AS THEY GET DRAGGED OVER THE BEDROCK, THE PARTICLES CARRIED IN THE GLACIER ACT AS CUTTING TOOLS ERODING THE BEDROCK IT FLOWS OVER. THE GRINDING ACTION OF THE ROCKS IN THE GLACIER CHANGES THE BEDROCK IN 3 IMPORTANT WAYS:
Notice the smooth polished bedrock with the parallel striations
The rocks carried inside the glacier go through abrasion as they are dragged over the bedrock.
UNLIKE RIVER ABRASION, GLACIAL ABRASION MAKES THE ROCKS BECOME SHARP AND JAGGED.
