Water Erosion: Experiment Two- Deposition

Question: What happens to the land that gets eroded?

Hypothesis: I think that the land changes shape or form.

Materials: 1 ruler, 1 bucket with a hole, one bucket without a hole, measuring cup, rough sand, clay, fine sand wood piece.

Procedure:1. Set up experiment by: having one side higher than the other, a ruler holding up a cup that the water was falling from, and a hole at the end of the tray where the water came out from.
2. We poured the water into the cup with the hole, so the water would slowly spill onto the sand and erode it.

Observation:
1. The water spread out in a puddle.
2. the water falling down has made a hole where it's landing
3.  The water started going down and going more in one direction more than the other.
4. The water has made a little valley.
5.  The valley has started to get wider and has turned into a canyon.
6. The sand has gone to the end of the canyon and has started to make a triangle shape.
7.  The canyon has started to get deeper, driving more sand to the bottom
8.  A lot of water has started to come faster when we add more water.
9.  A second valley has started to form.
10. First valley has mixed with the second valley be cause it's so wide.
Conclusion: The land gets pushed to the bottom of the river, making a triangular shape.
