What agent of erosion causes slump?

Gravity can also directly cause a phenomenon known as slump, in which large chunks of rock and soil suddenly break off and fall from the side of a hill or mountain. Unlike a landslide, rocks and soil no not roll down the side of a such landforms, but instead fall directly to the Earth below.

What erosion is slump?

A slump is a type of mass wasting that results in the sliding of coherent rock materials along a curved surface. In a slump, a portion of the mountain moves down a short distance.

Is a slump formed by erosion or deposition?

Landslides often occur on steep slopes in dry or semi-arid climates. The California coastline, with its steep cliffs and years of drought punctuated by seasons of abundant rainfall, is prone to landslides. Wet soil becomes slippery and heavy. Earthquakes often trigger landslides.

How does slump occur?

Slump moves materials as a large block along a curved surface. Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope.

Is wind an agent of erosion?

Wind is a powerful agent of erosion. Aeolian (wind-driven) processes constantly transport dust, sand, and ash from one place to another. Wind can sometimes blow sand into towering dunes.

Where does slump occur?

Slump is common where clay-rich materials are exposed along a steep slope. Such oversteepend slopes naturally occur on the outside of meanders along the Red River. Slump is typically identified as the downward movement of a block of earth material along some curved surface of failure.

What are characteristics of a slump?

Slump is a type of slide (movement as a mass) that takes place within thick unconsolidated deposits (typically thicker than 10 m). Slumps involve movement along one or more curved failure surfaces, with downward motion near the top and outward motion toward the bottom (Figure 15.14).

What is a slump in geography?

slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material.
