Percent Change

Sand:
Trial 1: (230 - 100)/100 = 1.3 * 100 = 130% increase
Trial 2: (185 - 100)/100 = .85 * 100 = 85% increase

Soil:
Trial 5: (375 - 100)/100 = 2.75 * 100 = 275% increase
Trial 6: (350 - 100)/100 = 2.5 * 100 = 250% increase

The sand is more prone to sliding because it had a lower amount of water increase needed to slide.
