Geologists distinguish among different types of mass wasting based on factors such as the
____________ of
the moving material and the rate of movement.
composition
One of the most problematic aspects of landslides is that large-scale, cataclysmic examples are the
norm,
whereas small-scale landslides are much more rare.
false
Mass wasting always involves a sudden movement of material downslope.
false
To the geologist, ____________.
all landslides are mass movements, but not all mass movements are landslides
Which of the following types of mass movement takes place most gradually?
creep
Which of the following types of mass movement is least coherent (most like a liquid)?
mudflow
Slumps typically arrive intact at the bottom of a slope.
false
Which of the following types of mass movement always travel down curved surface?
slump
Strictly speaking, which of the following types of mass movement is a landslide?
rock slide
Which type of mass movement includes a large proportion of ash derived from a volcanic eruption?
lahar
____________occur(s) when regolith moves slowly downslope due to freezing and thawing.
Creep
All types of mass wasting have approximately the same velocities.
false
, Between subaerial and submarine mass movements, we have a much better historical record of
____________.
submarine mvements
Which of the following types of mass movement is likely to move most rapidly?
rock slide
____________occur(s) where thawed sediments move downslope over permafrost.
Solifluction
____________occur(s) when debris or snow mixes with air to form a chaotic cloud.
Avalanches
____________occur(s) when a semicoherent mass of material moves downslope on a failure
surface.
Slumps
____________ are likely to occur along volcanic slopes.
Lahars
____________ may trigger tsunamis.
Submarine mass movements
A ____________ may form at the head of a slump.
failure surface
Submarine mass movements have been found along hot-spot volcanoes and active plate boundaries.
These
massive slumps have been attributed to ____________.
tectonic activity
In cold, dry mountainous climate, rock glaciers consisting of rocks held together by a smaller volume
of ice can slide down slopes.
true
The principle difference between a debris flow and a mudflow is the ____________.
grain size of the moving mass
The principle difference between a lahar and a mudflow is the ____________.
lahar contains pyroclastic debris from a volcanic eruption
The principle difference between a debris flow and a debris slide is the ____________.
debris flow contains abundant water, whereas the debris slide is dry
The principle difference between a slump and a debris slide is the ____________.
shape of the path taken by the moving mass
