WorksheetsShire's landslides quiz
Total questions: 18
Worksheet time: 9mins
Which of these is not a form of weathering?
Biological
Physical
Rotting
Chemical
Water from intense rains adds (a) to the earth on a steep slope, increasing the chances of landslides
Which factors will increase the chance of a landslide occuring?
Steep, barren slopes covered with a thick layer of soil
The dark forces of the underworld
Heavy Rains
7J jumping up and down at the top of a slope demanding it to move
What does "barren" mean?
Lacking in people called Barry
A place that is heavily weathered
Lacking in plants and other life
Somewhere cold
When are landslides most likely to occur in Hong Kong?
After Chinese New Year
The start of term
The end of the rainy season
During fire warnings
What other factors can increase the chances of a landslide occuring?
Cutting down trees for urban development
Mr Shire sitting down too fast
Earthquakes and other seismic activity
Strong winds
This can be a combination of chemical and physical weathering, but is caused by a biological process. A common example would be a tree root causing damage to building foundations. However, moss, lichens, fungus and mold can all break down objects.
Biological weathering
Physical weathering
Chemical weathering
SAUSAGES!!
A process where materials get broken apart without it changing their chemical composition. This can be seen in rivers carrying objects in a current - these objects can strike other objects and slowly disintegrate over time. This can be a result of humans also - think about old stairs where millions of people have passed over them and worn them down.
Physical weathering
Chemical weathering
Rotting weathering
A landslide is when...
Water gathering between loose soil and solid rock underneath causes rapid slipping of material down the slope.
Water gathering between big stones and little stones causes rapid rising of material up a slope.
Water gathering between loose soil and solid rock underneath causes nothing to happen.
What, if present on a steep slope, can decrease the chances of a landslide (even if it rains heavily)?
Buildings
Trees and other vegetation
People with umbrellas
Spongebob Squarepants
SAUSAGES!!
Why is Hong Kong quite susceptible to landslides? (check all that are correct!)
Human development on steep slopes
Too many hikers
Conditions which accelerate weathering
Frequent strong earthquakes
Which of these is NOT a predictor of landslides?
Distance to human development
Average rainfall per year
How big the slope is
Angle of repose
What is the outcome of increasing vegetation on a slope with regards to landslides?
It increases the chance of a landslide
It decreases the chance of a landslide
It does nothing
SAUSAGES!
What type of landslide prevention is this?
"This largely involves trying to move water to prevent a landslide, or sliding materials if a landslide does occur."
Barriers
Increasing Vegetation
Drainage & Diversion
Measures taken to strengthen a slope can help to prevent landslides. Sometimes this can take the form of concreting over a slope so that rainwater does not seep into the ground below.
Landslide barriers
Slope reinforcement
Increasing vegetation
What is this?
Landslide Barrier
Increased vegetation
An unfair advantage in a mud-fight
What can cause a landslide? Check all that apply!
Human development
Mr Shire's temper tantrums
Natural processes
Aliens
Godzilla (fighting aliens)
Can adding weight to a slope increase the chance of a landslide?
Yes
No
