What is a landslide?

Back

A landslide is the movement of rock, earth, or debris down a slope due to gravity.

Front

What are the main types of landslides?

Back

The main types of landslides include falls, topples, spreads, flows, and slides.

Front

What force is primarily responsible for landslides?

Back

Gravity is the primary force responsible for landslides.

Front

What is the angle of repose?

Back

The angle of repose is the steepest angle at which a sloped surface is stable, typically around 30 degrees for loose materials.

Front

What is a retaining wall?

Back

A retaining wall is a structure designed to hold back soil and prevent landslides.

Front

How do human activities contribute to landslides?

Back

Human activities such as deforestation, construction, and blasting can destabilize slopes and increase the risk of landslides.

Front

What is the role of vegetation in preventing landslides?

Back

Vegetation helps stabilize soil with roots, reducing erosion and the likelihood of landslides.

Front

What is a flow landslide?

Back

A flow landslide is a type of landslide where material moves down a slope in a fluid-like manner, often due to saturation.

Front

What is a topple landslide?

Back

A topple landslide occurs when a mass of rock or soil tilts and falls forward due to gravity.

Front

What is the impact of heavy rainfall on landslides?

Back

Heavy rainfall can saturate soil, increasing weight and reducing stability, leading to landslides.
