1
Q
Aggradational
A
- depositional slopes
2
Q
Degradational
A
- erosional slopes
3
Q
Transportational
A
- slopes where dominant process is transport
4
Q
Climatic geomorphology
A
- concept that diff climate zones produce a distinct set of geomorphological processes, which produce distinct geomorphological features
5
Q
Slope form
A
- aka slope shape
6
Q
Geological structure
A
- affected by characteristics of rocks inc. strength, lines of potential weakness + dip of rock
7
Q
Regolith
A
- irregular cover of loose rock debris that covers Earth
8
Q
Aspect
A
- direction slope faces
9
Q
Vegetation
A
- sig. role in slope processes by binding soil + intercepting pptn
10
Q
Avalanches
A
- mass movements consisting of v. fast flows of snow, ice + debris
11
Q
Slope processes
A
- physical processes (e.g. landslides, overland flow, soil creep) that operate on a slope
12
Q
Slides
A
- entire mass of material moving along a slip plane
13
Q
Slump
A
- form of mass movement occurring on weaker rocks, esp. clay, + have rotational movement along a curve slip plane
14
Q
Throughflow
A
- water moving down soil
15
Q
Waste
A
- unwanted material lacking in eco. value
16
Q
Pivoting
A
- change in slope angle in debris layer, w/o large-scale movement downslope
17
Q
Talus creep
A
- slow movement of fragments on a scree slope
18
Q
Rotational slide
A
- type of rockslide where sliding material follows a slip plane, + produces several steps or terraces
19
Q
Hazard assessment
A
- process of determining
- when + where hazards have occurred in past
- severity of physical effects of past events of a given magnitude
- frequency of events strong enough to generate physical effects
- what a particular event would be like if it were to occur now
20
Q
Falls
A
- mass movements occurring on steep slopes. esp. on bare rock faces where joints are exposed
21
Q
Surface wash/overland flow
A
- flowing of water over Earth’s surface once exceeds infiltration capacity
