In science we researched and presented our findings on erosion. I was assigned wave erosion. We found seven vocabulary words and made a model with a before and an after visual. In the picture, you can see that it is split in half with a manilla folder. That shows the before and after of wave erosion. Before, is more of a cliff and over time waves broke down and carried sediment away making the after half, looking longer and creating a waterfall from the stream that was there.
