This photo was taken down by the Hudson River at 3:00, on 12/6/14. This is a youthful stream because the stream had a high velocity and had cutting action through bedrock. Youthful streams can carry all sorts of sediments.
This photo was also taken around the Hudson River at 3:10, on 12/6/14. I know that this is soil creep because the soil creep was slow, and had imperceptible movement of soil down hill. It is very hard to see the actual process of Soil Creep.
This photo was taken on the road to Black Rock at 3:30, on 12/6/14. I know that this is a landslide because these rocks are all scattered on the hill going in a downward motion. Landslides can be very deadly, at times if they occur sudden and are very fast moving.
This photo was taken on the shoreline of the Hudson River at 3:20, on 12/6/14. I know that this is a rocky shoreline because the rocks are scattered all along the shore and the rocks are jagged and sharp. These shorelines can also stop flooding because of their elevation.
This photo was taken at Black Rock at 3:35, on 12/6/14. This is a v-shaped valley because this is a river valley and it produced steep walls and a bottom. These valleys carry very fast moving rivers.
This photo was taken at the Hudson River at 3:25 on, 12/6/14. This is a glacial erratic because the rocks are in the middle of a field and a river is behind the rocks. Glacial Erratic rocks can appear anywhere where a river is remotely close.
This photo was taken on the road to Black Rock at 3:40, on 12/6/14. This is a cut bank because this is the outside bank of a water channel, which is continually undergoing erosion. Cut banks can be eroded much more quickly if the river is flowing faster than if it isn't.
This photo was taken at the Hudson River at 3:45 on 12/6/14. This is a beach because sand is present along with water all around it. Beaches don't have to be associated with the Atlantic or Pacific oceans, they can be rivers like this one, that can also hold beaches.
This photo was taken at the Hudson River at 3:10, on 12/6/14. This is a flood plain because if this particular river floods this will help stop the flood and all the water will go onto the plain. Flood Plains play a huge role in protecting houses, buildings, and even people.
This photo was taken at the Hudson River at 3:25, on 12/6/14. This is a mature stream because there is not a lot of velocity and the shape is gentle, not a v. It is also not very steep. Mature streams are more common with big areas of water.
