Types
Bits of rock fall off the cliff face.
What is rockfall?
............... pulls sediment down and causes mass movement/ landslides.
What is gravity?
Is this destruction of homes and property a natural or human environment effect?
What is human environment effect?
Planting vegetation on slopes where roots will help bind and hold soil together.
What is revegetation?
In wet climates the continual wetting of soil on slopes allows it to slide easily, and the material travels downhill in small steps.
What is soil creep?
The gradient/ angle of a slope is usually this way for mass movement to occur.
What is steep?
Loss of life and injury is a natural or human environment effect?
What is human?
What are Gabion baskets?
Heavy rain or a flood, a burst river bank or a collapsed dam may saturate sediment and turn it into a river of much, which is then propelled downslope by gravity.
What is mudflow?
How does deforestation cause mass movement?
What is no infiltration/ no roots to bind soil?
What does mass movement cause harm to when farm land becomes inaccessible and/ or cover with debris?
What is agriculture?
Reduce erosion by dividing slope into steps, slowing runoff.
What is terracing?
Where there is only seasonal rain, or occasional downpours, a lot of rock and soil can accumulate on a slope. When it is heavier and lubricated by rain, it cans suddenly give way and create a .........
How can building on slopes increase the possibility of landslides?
What is adds weight, increase slope angle, deforestation?
Landslides can affect river ecosystems and water quality by polluting bodies of water with ........
What is debris or sediment?
A drilled nail or anchors placed into slopes to stabilise the slope.
What is a rock bolt?
Soft materials (clays or sands) overlies more resistant rock.
What is slumping?
For mass movement to occur ................... for must exceed ................... force.
What is gravitational, resisting?
The cost when infrastructure is being repaired, replaced or maintained after a landslide.
What is economic loss?
What is rip rap?
