Walking along the beach of Cape Cod, Massachusetts, scientist Britt Argow points out layers of different-sized sediments. These provide clues to what deposited the sand and gravel that make up Cape Cod. To deposit this amount of sediment would normally take an enormous river; but there is no such evidence that such a river ever flowed in the Cape Cod area. Featured Scientist: Sherilyn Williams Stroud, Ph.D.
Grades 5-8 Standard D. Landforms are the result of a combination of constructive (sedimentation, volcanoes) and destructive forces (weathering and erosion).
