Which of the following types of landslides involves backward rotation of the slipping material?

Correct option is C

The correct answer is (c) Slump.
• A slump is a type of landslide where the mass rotates backward along a curved slip surface.
• The movement is rotational rather than translational.
• It commonly occurs in soft rock or clay-rich slopes.
Information Booster:
• Slump is also called a rotational landslide.
• Common in regions with steep slopes and heavy rainfall.
• Frequently observed in road cuttings and river banks.
Additional Knowledge:
• Rockslide involves downward sliding without rotation.
• Rock fall is free fall of rock fragments.
• Debris fall consists of loose soil and rock material falling vertically.
