What role does excessive rainfall play in the occurrence of landslides?

Excessive rainfall saturates the soil, reducing its strength and increasing its susceptibility to slope failure. Signup and view all the answers

How do human activities contribute to the formation of landslides?

Human activities such as deforestation, road construction, and excavation remove stabilizing vegetation and alter drainage, leading to unstable slopes. Signup and view all the answers

What is a sinkhole and how does it typically form?

A sinkhole is a depression in the ground that forms when the surface collapses into an underground void created by the dissolution of soluble rocks. Signup and view all the answers
