In this experiment my group and I wanted to see how the type of dirt (compacted or loose) and animals would affect the formation on rivers. We used 50mL of water on the both of the experiments.
To see how the types of dirt affected river flow we used diatomaceous earth. We broke up the dirt in order to make the loose dirt but kept some of the dirt still compacted together. After we had all the dirt the way we wanted it, we poured the water into the dirt to see which one made the most erosion. When we were done pouring all the water into the tub we look at the results and found out that with more compact dirt, the river would flow longer but not as deep, and with the loose dirt we found that the river would form shorter but much deeper.
To see how animals affected how the formation of water, we took plato and made little animals and put them in the way that we thought the river would flow. We used 50mL of water for this experment as well. After pouring all the water we found that the animals didnt have any difference in the formation of water. The water just went right around the animal and then went back on its normal route.
