We also learned swamps are just floating land. Mr. Metz, in Becca's group, was leaning against a tree when Susan, the group leader, suddenly said to look at the tree. That was when we noticed the tree moving. In Lizzie's group, Dave, another leader, lifted up one of the the trees and showed them that it was on an island and that it was floating in the water. When we reached the middle of the path, Dave showed how erosion works using sticks.
Erosion is when water cuts away at soil and rocks.
Erosion is a part of succession because it changes land forms. Now we are trying to find a way to prevent erosion so that our Bay, that has existed for so long, doesn't disappear.
