Rockin' and Rollin': How Landforms Change

Your team of 3 will research constructive and destructive forces that a landform underwent to appear the way it does today. Your group will create a PowerPoint presentation describing theories about how your particular landform transformed.  Also, you will use materials such as sand, rocks, gravel, soil, ice, and water to demonstrate those transformations to further help your classmates understand the changes the Earth's surface undergoes.
