Question

Name any two causes of landslide.

Answer 1

Answer:

Weathering is the natural procedure of rock deterioration that leads to weak, landslide-susceptive materials. ...

Erosion caused by sporadic running water such as streams, rivers, wind, currents, ice and waves wipes out latent and lateral slope support enabling landslides to occur easily.

Answer 2

hey buddy..

• Water: Perhaps the most common trigger of a landslide, water reduces the friction between the bedrock and the overlying sediment, and gravity sends the debris sliding downhill. In sand and clay soils, a small amount of water may increase stability. You've likely seen this when building a sand castle or working with clay. However, the sediment gets heavier as more water is added and that can cause it to flow downhill. This is why many landslides occur after rainstorms

• Earthquakes: If the Earth's crust vibrates enough to disrupt the force of friction holding sediments in place on an incline, a landslide can strike. Seismic activity can also make it easier for water to seep into the soil, further destabilizing the slope.

• Wildfires: Plants help keep the soil stable by holding it together like glue with their roots. When this glue is removed, the soil loosens, and gravity acts upon it much more easily. The loss of vegetation after a fire makes the razed land susceptible to slides.

• Volcanoes: Several characteristics of volcanoes make them fertile starting points for especially destructive landslides. On the next page, you'll learn just how powerful these volcanic landslides can be.
