River Formation

My group and i tested how geysers effect the formation of rivers. My hypothesises that to diatomatious earth a river would form easily. To the pure gravel i though nothing would happened. And to the sand mixture i thought a river would be formed with a little resistance. When we tested on the diatomatious earth a river was formed easily. On gravel nothing happened. And with the sand mixture a river was formed with a little resistance.






We also tested overflowing lakes. My hypotheses was that in diatomatious earth the lake will be destroyed. I thought in gravel it will just leak through. And in the sand mixture a river might form. When we tested it, diatomatious earth fell apart. Gravel let watter leak through. And sand let a small river form.
