Folding, Faulting, and Denudation
Test Review Topics
This first set of points is from the introductory slide show.
-
forces in balance - what does this mean?
-
folding: compression; types of folds - anticline, syncline - know how
to do simple diagrams
-
faulting: normal (down), reverse (up), strike-slip (sideways), horst (block
mountains), graben (rift valley) - know how to
do simple diagrams
-
what is denudation; what are weathering/erosion, transportation,
deposition.
This set of points is from the Rock Deformation
slide show.
-
rock deformation
-
differential stress/erosion
-
elastic vs plastic; rupture
-
brittle vs ductile rocks
This set of points is from the Mass Wasting
slide show
-
mass wasting: soil creep; earthflow; Leda clays; mudflows; landslides
-
what is mass wasting - rate affected by: slope, gravity, water, structure
-
Types of mass wasting - creeping (slow, gradual slope), flowing (steeper
slope, wet conditions), sliding/avalanche (steep slopes, erosion, not wet, can
be dangerous), slumping (similar to creeping but the movement is much like
slumping down in a chair, the ground does not travel far).
-
Frank Slide Activity - what happened, why.
-
BC Avalanches - what happened, why
This set of points is from the Gradation and
the Weathering Processes slide show.
-
geomorphology
-
gradational process: driven by solar energy; gravity and kinetic energy
-
peneplanation
-
weathering: 3 types of chemical (decomposition) and 5 types of mechanical (disintegration)
-
mechanical weathering processes: freezing of water (frost action, frost wedging); changes of temperature;
pressure change;
salt crystal growth; action of plants and animals; release of pressure
(exfoliation/domes)
-
chemical weathering processes: Solution
(underground - Karst); Oxidation (rusting); Hydrolysis (above ground - clay soil minerals)

The
Niagara Escarpment (An area in
Conflict)- how it was formed (diagram); why the Falls are where
they are (see the image here)
Very general knowledge on the following Headings:
Planning
- Core - Buffer - Transition Areas
- Too protect and maintain natural environment
- Building regulations, Public Parks, Waste Disposal, Road Access
- Protect farming and forestry
- Protect the ecological and historical aspects.
Protection
- Protect the Biosphere
- Mining and Agriculture - too many people
- Niagara Escarpment Commission - Niagara Act - 1973
Issues
- Mineral Resource Extraction
- Lot Creation
- Urban Sprawl
- Clash of Values
Facts
- Extremely old
- Mosaic of Land Use - cities, farms, forests, Mines, Wetlands, Escarpment
- Balance between conservation and development
- Tourism, resources, scenic landforms
Interests
- Public vs. Private
- Private landowners and businesses favour development
- Environmentalist of course are against development
- All agree that a plan has to be in place.
Geology.
- Sapping
- syncline
- erosion
- rivers, glaciers, wind
