The dynamic platform supports the exploration of Digital Elevation Models (DEMs) for the US and territories at a mixture of scales, including 1 meter DEMs. Observe the amount of sediment at the bottom of each hill after the storms.Elevation aspect map rendered in the 3DEP Demonstration Elevation Viewer. Use the solo cup with the holes punched in the bottom to “rain” one cup of water on the first hill, then the second hill. Try to plan how to keep as much sediment on your hill. Work with your team to cover the hills with sand, then gravel. Each hill should be made out of two sticks of modeling clay. Procedure Work with your team to create two clay hills. Materials 4 bars of modeling clay – two for each “hill.” Two tin baking pans 1 cup of sand ½ cup of gravel 2 cups of water, one for each rain storm/hill 1 solo cup with 6 small holes punched in the bottom Do you think the hill with the steeper slope will have more erosion? Or will the hill with the less steep slope have more erosion? Hypothesis Use what you already know about gravity and forces. Finally, you will observe and, if necessary, measure to see which “rainstorm” deposited the most soil at the bottom of the hill.Then, you will use a cup with the same amount of holes punched in the bottom (controls) that are the same size (controls) to drizzle water over the soil on the hills to simulate rain.
