Which factor can lead to a landslide?

Low vegetation coverage can indeed lead to a landslide because vegetation plays a critical role in stabilizing soil. Plant roots help bind the soil together and anchor it, making it less susceptible to erosion. When vegetation is sparse or absent, the soil lacks this critical structural support, which can increase the risk of landslides, particularly during heavy rainfall or rapid snowmelt. In addition, without plants to absorb water, the saturation of the soil can reduce its stability, leading to potential slides.

In contrast, sturdy soil composition generally lends to better stability, while stable weather conditions decrease the likelihood of landslides since extreme weather can often trigger such events. Horizontal soil layering typically helps with drainage and stability, reducing the chance of landslides.
