Answer 2

c) Landslides.

Landslides are "mass wasting," which denotes any downward sloping motion of soil and rock under the influence of gravity.

Explanation-

• Rainfall will cause the softening of rock and soil, reduction of the mechanical strength of rock and soil mass, and the slope will become unsteady and eventually form disasters like landslide.
• Rainfall patterns are influenced by the topography of mountain region as they act as a barrier to strong winds and therefore receive heavy rainfall on their windward side.
• Landslides are very common around the world, but the danger of landslides caused by rainfall tends to be much greater in tropical mountainous regions like those in the Philippines, Central and South America, and southeastern Asia.
