Question

Which of these is NOT a contributing factor to landslides? a) water b) unstable subsurface c) trigger d) gravity​

Answer 1

All the options are a contributing factor to landslides. None of the options is not a contributing factor to landslides.

• Water is the primary contributing factor to landslides. High rainfall, melting snow, changing water levels in reservoirs, and change in groundwater levels are all causes of landslides.
• Unstable surfaces are formed due to both natural and human activities and such surfaces are prone to landslides.
• Triggers like volcanic eruptions, earthquakes, and floods also result in landslides.
• Weakened slopes are prone to landslides because of the action of gravity.
