The correct answer is Slump.

Key Points

• A slump is a type of landslide characterized by the backward rotation of the slipping material along a curved surface.
• This rotational movement often creates a concave-upward shape in the displaced material and leaves a crescent-shaped scarp at the top.
• Slumps occur when a slope becomes unstable due to water infiltration, weak soil, or geological disturbances.
• They are commonly found in areas with clay-rich soils, as clay can become saturated and lose its cohesive strength.
• Unlike other types of landslides, slumps usually involve large blocks of material moving as a coherent unit, rather than chaotic debris flow.

Additional Information

• Rockslide:
• A rockslide involves the rapid movement of large masses of bedrock downslope.
• It typically occurs on steep slopes where rock layers are weakened by fractures or weathering.
• Unlike slumps, rockslides do not rotate; instead, they slide along a planar surface.
• Example: The Frank Slide in Canada (1903).
• Rock fall:
• A rock fall is characterized by the free fall or bouncing of individual rocks from steep cliffs or slopes.
• It is often triggered by freeze-thaw cycles, erosion, or seismic activity.
• Rock falls are the fastest type of landslide and can cause significant damage.
• Example: Yosemite National Park has frequent rock falls due to its granite cliffs.
• Debris fall:
• Debris falls involve the rapid downward movement of unconsolidated material, such as soil, rocks, and organic matter.
• They are often triggered by heavy rainfall or earthquakes, which destabilize the slope.
• Debris falls are chaotic and lack the coherent rotational movement seen in slumps.
• Example: The 2014 Oso landslide in Washington, USA, was a debris fall.
• Characteristics of Slumps:
• Slumps are slower than rockslides and debris falls due to their rotational movement.
• They are common in areas with poorly consolidated sediments, especially in regions prone to water saturation.
• Preventive measures include slope stabilization, proper drainage systems, and vegetation cover to improve soil cohesion.

Important Points

• Types of Landslides:
• Falls: Free-falling movement of material from a cliff or steep slope.
