C Correct answer
Explanation

Mangrove forests have complex root systems that stabilize shoreline sediments, dissipate wave energy, and trap coastal soils, thereby effectively preventing coastal erosion.

Which of the following comes under the phenomena of mass movement?

A. Soil creep

B. Landslide

  1. Only A

  2. Only B

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mass movement or mass wasting is movements of masses of bodies of soil, bedrock, rock debris, soil, or mud which usually occur along steep-sided hills and mountains because of the pull of gravity. This slipping of large amounts of rock and soil is seen in landslides, mud slides, and avalanches.

Landslides occur when masses of rock, earth, or debris move down a slope. They may be very small or very large, and can move at slow to very high speeds. However, slow movement is also seen in the gradual downhill creep of soil on gently sloping land.

_______ are caused by the instability of rock, heavy and torrential rainfall, tremor, etc.

  1. Landslides

  2. Tsunamis

  3. Earthquakes

  4. Floods
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Landslides are triggered by factors that reduce the stability of a slope, such as heavy rainfall, tremors (earthquakes), or the inherent instability of the rock/soil structure.
