What is Mass Wasting?

Back

Mass wasting refers to the movement of soil and rock down a slope due to gravity. It includes various processes such as landslides, rockfalls, and mudflows.

Front

Define Creep in the context of mass wasting.

Back

Creep is a slow, gradual movement of soil and rock down a slope, often caused by freeze-thaw cycles and wetting and drying.

Front

What is a Rock Fall?

Back

A rock fall is a rapid mass wasting event where rocks detach from a steep slope and fall freely to the ground.

Front

Explain Mudflow.

Back

Mudflow is a type of mass wasting that involves the rapid flow of water-saturated soil and debris down a slope, often triggered by heavy rainfall.

Front

What is a Slump?

Back

A slump is a type of mass wasting characterized by the downward movement of a block of material along a curved surface.

Front

Identify the factors that influence mass wasting.

Back

Factors include gravity, water content, slope angle, vegetation, and geological materials.

Front

How does vegetation affect mass wasting?

Back

Vegetation helps stabilize soil with roots, reducing the likelihood of mass wasting. Removal of vegetation can increase vulnerability.

Front

What role does water play in mass wasting?

Back

Water can increase the weight of soil, reduce friction, and lead to saturation, making slopes more prone to failure.

Front

Differentiate between rapid and slow mass wasting processes.

Back

Rapid processes include landslides and rockfalls, while slow processes include creep and solifluction.

Front

What is Solifluction?

Back

Solifluction is the slow, downhill flow of water-saturated soil, often occurring in permafrost regions.
