How does deforestation influence mass movement?
How does deforestation influence mass movement?
It loosens soil, increasing erosion and landslide risk.
What are the effects of urbanisation on land stability?
What are the effects of urbanisation on land stability?
It increases landslide risk with heavy structures on slopes.
How does mining contribute to mass movement?
How does mining contribute to mass movement?
It destabilises land, leading to rockslides and mudslides.
What role does agriculture have in mass movement risk?
What role does agriculture have in mass movement risk?
Poor practices expose soil, increasing erosion and landslides.
How does road construction affect slope stability?
How does road construction affect slope stability?
Cuts into ground may trigger landslides and soil slides.
What impact does climate change have on mass movement?
What impact does climate change have on mass movement?
It increases extreme weather events, raising landslide risk.
Example of deforestation leading to mass movement?
Example of deforestation leading to mass movement?
Cleared forests cause more frequent landslides in rainy areas.
Example of urbanisation causing landslides?
Example of urbanisation causing landslides?
Improper construction in San Francisco triggers landslides.
Example of mining leading to mass movement?
Example of mining leading to mass movement?
Mining in Chile collapses waste piles, causing landslides.
How does overgrazing affect landslide risk?
How does overgrazing affect landslide risk?
It exposes soil to erosion, increasing likelihood of landslides.
