Which is not a factor that influences mass movements?
water
weight
soil type
time

Option (4)

Explanation:

Mass wasting usually refers to the downward motion of the soil particles or rock materials under the influence of gravity. These are triggered due to various factors such as-

The presence of water in the soil as it easily allows the materials to flow downward along a slope with less friction. The weight of the material also influences the mass-wasting process as the heavier and unstable materials tend to flow downward. The type of soil also is equally important, because the loose and unconsolidated materials will be easily washed away during landslides.

Thus, time is the factor that does not influence the mass movement.

Hence, the correct answer is option (4).
