Answer:
All options are possible reasons for causing a landslide.
Explanation:
Landslide is a geological phenomenon that occurs when the soil is moved due to the occurrence of external factors, causing sediments and even rocks to become unstable and slide downwards. This phenomenon is very dangerous, as it can bring down houses, buildings and any other structure causing burial.
A landslide can happen for several reasons, among which can be cited:
- River erosion may have made the slope unstable.
- Heavy rains may have made the materials heavier and lubricated the slip surface.
- Rock layers were dipping toward the valley, parallel to the slip surface.
- A large housing development was built in the area, making the slope unstable.
