Mass Movements

Front

What is mass movement?

Back

Mass movement refers to the downward movement of soil, rock, and debris under the influence of gravity.

Front

What factors increase the likelihood of mass movement?

Back

Factors such as heavy rainfall, earthquakes, and the addition of water to soil can increase the likelihood of mass movement.

Front

What is a slump in the context of mass movement?

Back

A slump is a type of mass movement where a mass of loosened rock and soil moves downhill in one large chunk.

Front

What is creep?

Back

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

Front

What is a rock fall?

Back

A rock fall is a type of mass movement where rocks fall rapidly from a steep slope or cliff.

Front

What is a mudflow?

Back

A mudflow is a rapid flow of water-saturated soil and debris down a slope.

Front

How does water affect soil stability on slopes?

Back

Adding water to soil on slopes increases the probability of mass movement by reducing friction and cohesion.

Front

What is the difference between a landslide and a slump?

Back

A landslide involves a rapid movement of a large amount of earth material, while a slump involves the downward movement of a mass of rock and soil in one piece.

Front

What role does vegetation play in mass movement?

Back

Vegetation helps stabilize soil with roots, reducing the likelihood of mass movement.

Front

What is the impact of human activities on mass movement?

Back

Human activities such as deforestation, construction, and mining can increase the risk of mass movement.
