How is it possible for a landslide to occur without a trigger?
A)Heating from geothermal processes weakens the rock.
B)Long-term weathering weakens the rock past the strength necessary to maintain stability.
C)Slopes are shaken by earthquakes and the materials are loosened.
D)Water migrates along the sediment particles, reducing friction between them.

Question

Quizplus · Accepted Answer

Over time, weathering processes caused by wind, rainfall, and freeze-thaw cycles can gradually weaken rocks and soil on a slope, reducing their stability until a landslide occurs. This type of landslide is known as a slow or creep landslide, and while it may not have a sudden trigger, it can still cause significant damage over time.
