Which of the following is a primary cause of landslides in the Himalayan region?
- Flat terrain
- Deforestation, unscientific construction, and heavy rainfall
- Low seismic activity
- Absence of rivers
Answer: Deforestation, unscientific construction, and heavy rainfall
Removal of vegetation, slope cutting for roads/buildings, and intense monsoon rains destabilize slopes, triggering landslides in fragile Himalayas.
