Front

What is creep in the context of mass movements?

Back

Creep is the slowest type of mass movement, characterized by the gradual downhill movement of soil and rock.

Front

What happens during a rock slide?

Back

During a rock slide, large masses of rock break free from a slope and slide down, often crumbling and disintegrating as they move.

Front

What human activities contribute to mass movement?

Back

Activities such as open cast mining, clearance of vegetation, dredging, and agricultural practices contribute to mass movement.

Front

Define landslide.

Back

A landslide is a sudden and fast movement of rock, earth, or debris down a slope.

Front

What is the difference between a mudflow and a debris flow?

Back

A mudflow is primarily composed of water and fine particles, while a debris flow contains larger rocks and debris mixed with water.

Front

What factors can trigger mass movements?

Back

Factors that can trigger mass movements include heavy rainfall, earthquakes, volcanic activity, and human activities.

Front

What is the role of vegetation in preventing mass movements?

Back

Vegetation helps to stabilize soil with its root systems, reducing the likelihood of mass movements.

Front

What is a slump?

Back

A slump is a type of mass movement where a section of soil or rock moves down a slope in a rotational manner.
