What is Erosion and How is it Different than Weathering  Weathering is the breaking down of rock into smaller pieces.  Erosion is the MOVEMENT of these.

How do Glaciers change the earth’s surface? By Mrs. J

Weathering and Erosion Effects Overview Glaciers Weathering and Erosion Effects Deposition Effects

Glaciers Compressed snow layers Cold year-round: advance, retreat Moved by gravity and pick up sediment Ice mass moves slowly (1-2 in./day) Changed land surface over many years

Weathering Effects Weathering Rocks broken into smaller pieces Ice crushes rocks into sediment Rocks grind other rocks Effects Glacial Striations = long scratches Glacial Polish = flatten and shine rocks

Erosion Effects Erosion Pluck rocks and pick up sediment Carry sediment downhill Effects Horns = ice carves out sides of peak Missing sediment = empty space U-Shaped valleys = half-pipe shape

Deposition Effects Deposition Relocates sediment and rocks Effects Moraines = piles of rocks or sediment Kettles: ice fills area and melts Erratic: material different from things around it
