How does the blasting technique used by mining operations trigger landslides?
Blasting causes thermal expansion in rocks, affecting the stability of hillsides.
Blasting sets fire on the land mines.
Blasting creates hydrostatic pressure that forces the soil to move.

Why is planting trees on a slope a good idea to prevent landslides?
Trees serve as a habitat of animals.
Trees hold the soil in place.
Trees cool the climate.
Trees provide a tourist attraction.
How are quarrying and slash-and-burn method alike?
