Questions!

When we went to Wissahickon park I learned mostly about erosion and I learned that there are bikers riding up and down the trail we were walking on. What I learned about erosion is it is basically land being worn down into the ground because of weather. A littler bit of erosion took place at Wissahickon park. I also noticed that there were bikers riding up and down the trail i never knew that.What I think could have been better is the space to walk up the trail. It was a little tight because we had to stay out of the way for the bikers. I would have liked to learn more about the river. We were mostly learning about the land.
