How does water affect mass-wasting processes?
What will be an ideal response?
Water destroys particle cohesion by filling pores in sediment (saturation), which triggers mass wasting. However, when water only partially fills the pore spaces, it actually increases cohesion. Water also adds mass to the material, and this mass alone may be sufficient to cause gravity to act on a slope.
