Which of the following are considered triggers for mass movement events? Choose all that apply. View Available Hint (s) oversteepening of the slope o addition of vegetation to the slope desiccation (drying) of the material o oversaturation of the material O ground vibrations

Options (1), (3), (4), and (5)

Explanation:

The mass movement is often referred to as the downslope movement of materials such as rock particles, soil and sand under the influence of gravity. The factors that are responsible for the mass movement are gravity, steepening of the slope, lack of vegetation cover, oversaturation of soil or materials. They can also occur during an earthquake as the ground shakes. These mass wasting is also considered as the mass wasting process.

This mass wasting process occurs in the following ways-

(1) Falls

(2) Slides

(3) Creeps

(4) Flows

Thus, the correct answers are options (1), (3), (4), and (5).
