Question

Identify the incorrect statement regarding landslides and their causes.

1. Landslides are exclusively slow-moving geological phenomena that pose little immediate threat.
2. Gravity is the fundamental force responsible for initiating and driving all types of landslides.
3. The saturation of ground due to melting snow, combined with the snow's weight, can increase landslide risk.
4. The removal of protective soil layers and vegetation through erosion can significantly weaken a slope, making it prone to landslides.

• A. iii, iv
• B. എല്ലാം
• C. i മാത്രം
• D. ഇവയൊന്നുമല്ല

Answer 1

Answer:

C. i മാത്രം

• Landslides vary greatly; some can be very slow, but others can move rapidly and cause immediate and severe damage.

• Gravity is the fundamental force that drives all landslides by pulling soil, rock, and debris downslope.

• Saturation of soil from melting snow and the added weight increases landslide risk by reducing slope stability.

• Removal of protective soil layers and vegetation through erosion weakens slopes, making them more prone to landslides.
