Steven and his sister Sasha are making observations about erosion and the rate of movement of materials. They are looking at different bodies of water and how small rocks are being moved. Sasha took a piece of broken rock about 2 cm and threw it into each body of water to observe what happened. They followed the material if it moved to get a distance of travel. They recorded the data below.

What observations can be made regarding the bodies of water and distance eroded materials travel?

Scientists are studying different cliff faces and how their rates of erosion are affected by the slope of the rock formation. Meredith wants to come up with a way to extend the amount of time that it takes for a cliff face to be completely eroded. What can Meridith recommend doing after reviewing the relationship between slope and erosion rate in the table below?
