What is mass movement?
The movement of rock and soil downslope due to gravity
What is the main force behind mass movement?
Gravity
What factors increase mass movement risk?
Steep slopes, water saturation, and lack of vegetation
How does water influence mass movement?
It adds weight and reduces friction between particles
What is a landslide?
A rapid downslope movement of rock and soil
What is creep?
A slow, gradual movement of soil downhill over time
What is a slump?
A mass movement where material moves as a unit along a curved surface
What is the difference between rapid and slow mass movement?
Rapid occurs suddenly, slow occurs gradually over time
Why is mass movement dangerous?
It can destroy infrastructure and reshape landscapes quickly
What role does gravity play in mass movement?
It pulls materials downslope when stability is lost
