PPT-Weathering Weathering The process of breaking down rock by other substances at Earth’s

Erosion The carrying weathered rock from one location to another Mechanical Weathering Rock is physically broken down Smaller pieces have same composition Chemical Weathering Rock is chemically broken down. Have the landforms undergone changes?. What do you think caused the changes?. How long do you think the changes may have taken?. Were the changes constructive or destructive?.
