FC: erosion and weathering by John Kostelec
1: This is abrasion because all the rock are bumping into each other when the stream pushes them.This was at the lower falls. This is physical weathering.
2: This is root action because the roots of the plant work their way into cracks in the rock, enlarging the rock. This is physical weathering.
3: This is an example of frost action because the water would get in the cracks and freeze and expand the rock.
4: This is erosion because the water made a hole in the rock by eroding it. Now it is a stream.
5: This is a living organism because there is moss growing on the rock. This is chemical weathering.
