Each of those images has the same number of pixels between four and twelve ounces.
I added 12oz of water to 12oz of dirt and got 17.17 ounces of muddy water, about 8oz of watery mud and 9.17oz of dirty water.
As for the mud composition, it looks like an ounce or less of... mud... another ounce or less of... mud... and then about ten ounces of... mud...
Which ones are gravel, sand, silt, and clay?
Am I missing a level?
