GEOLOGY

Detailed explanation-1: -A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of “mass wasting, ” which denotes any down-slope movement of soil and rock under the direct influence of gravity.

Detailed explanation-2: -Rockfalls are a newly detached mass of rock falling from a cliff or down a very steep slope. Rockfalls are the fastest type of landslide and occur most frequently in mountains or other steep areas during early spring when there is abundant moisture and repeated freezing and thawing.

Detailed explanation-3: -The two major types of slides are rotational slides and translational slides. Rotational slide: This is a slide in which the surface of rupture is curved concavely upward and the slide movement is roughly rotational about an axis that is parallel to the ground surface and transverse across the slide (fig.

Detailed explanation-4: -continuous creep – where the soil and rock debris isn’t strong enough to resist gravity. progressive creep – where the soil and rock debris suddenly reaches a critical state such that it will fail due to other factors.

Detailed explanation-5: -falls. topples. slides (rotational and translational) flows.
