The sum of all the underlying causes can push a slope to the brink of failure,and then an immediate cause may trigger the movement.Triggers for mass movements include ______________.

Question

Quizplus · Accepted Answer

All of these choices can trigger mass movements. Heavy rains can saturate soil and increase water pressure, making slope materials more unstable. Earthquakes can shake and weaken the slope, causing it to fail. Thawing of frozen ground can destabilize the slope as the frozen ground melts and becomes more waterlogged. Construction projects of humans can alter the slope's natural stability, making it more vulnerable to failure. Therefore, all these choices are correct.
