Percent change in the amount of water

Jaclyn Salevsky White B3

It took 40 milliliters of water to cause mass movement for both sand and the potting soil.
Sand:
40 divided by 100= 40 multiply by 100= 40%
Potting Soil:
40 divided by 100= 40 multiply by 100= 40%
It shows that the change for the sand and the potting soil was 0%. Which means that both were not more prone to slide.
