Landslides

What is a landslide?

• A sudden flood caused by heavy rain.

• The movement of rock, earth, or debris down a slope due to gravity.

• A type of earthquake that occurs underwater.

• A geological formation created by volcanic activity.

What are the environmental effects of landslides?

• Habitat destruction, soil erosion, and water pollution.

• Increased biodiversity and improved soil fertility.

• Enhanced water retention and reduced erosion.

• Creation of new habitats and increased vegetation.

What is the difference between a landslide and an avalanche?

• A landslide involves earth and rock, while an avalanche involves snow and ice.

• A landslide occurs in water, while an avalanche occurs on land.

• A landslide is a sudden flood, while an avalanche is a slow-moving glacier.

• A landslide is caused by earthquakes, while an avalanche is caused by volcanic eruptions.

What is the role of vegetation in preventing landslides?

• Vegetation helps stabilize soil with roots, reducing the risk of landslides.

• Vegetation absorbs water, increasing the risk of landslides.

• Vegetation provides food for animals that dig into the soil, causing instability.

• Vegetation blocks sunlight, preventing soil from drying out and leading to erosion.

What role does rainfall play in landslides?

• Heavy rainfall can saturate soil, increasing the likelihood of landslides.

• Rainfall has no effect on landslides.

• Rainfall only affects the surface of the soil, not the stability.

• Rainfall decreases the risk of landslides by compacting the soil.

What safety measures can be taken to prevent landslide damage?

• Proper land use planning, drainage systems, and vegetation can help mitigate landslide risks.

• Increasing the slope of hills to allow for better drainage.

• Building more roads to improve access to landslide-prone areas.

• Planting only non-native species to stabilize the soil.

How do landslides affect the Earth’s surface?

• They create new mountains.

• They can block roads, destroy houses, and alter landscapes.

• They increase soil fertility.

• They have no significant impact on the surface.

What is the impact of landslides on infrastructure?

• Landslides can cause major damage to roads, bridges, and buildings.

• Landslides have no significant impact on infrastructure.

• Landslides only affect agricultural land.

• Landslides improve the stability of nearby structures.

Can landslides be predicted?

• Yes, they can be accurately predicted.

• No, landslides cannot be accurately predicted.

• They can be predicted with some degree of accuracy.

• Only in certain conditions can they be predicted.
