Question

heavy rainfall sometimes trigger landslide near mountaians? give scientific reason​

Answer 1

Explanation:

Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability. Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity. Excessive water is thought to be one of the most common triggers for landslides.

Answer 2

Answer:

It is because during an intense rainstorm ,the bedrock will keep the rain trapped in the top soils of silt and sand .As the topsoil becomes saturated and heavy ,it will start to slide over the bedrock and become shallow .This way rainfall trigger landslide near mountains
