Engineering Geology Final Exam
Questions and Answers 100% PASS
Mass wasting/movement - CORRECT ANSWER-is downhill movement of
masses of bedrock, rock debris or soil, driven by the pull of gravity
How mass movements are classified - CORRECT ANSWER-based on the type of
movement and the type of slope material
Common types of mass movements and how they differ: creep - CORRECT
ANSWER-slowing moving flows of moving material
Common types of mass movements and how they differ: falls - CORRECT
ANSWER-mass of rock, debris, or soi seperates from a steeply sloping surface and
rapidly moves down slope by free fall, bounding, or rolling
Common types of mass movements and how they differ: topple - CORRECT
ANSWER--material pivots about a fixed point
- Develop in fractured or jointed rock or cohesive-soil slopes
-Freeze-thaw causes rotation about a fixed pivot point
, Common types of mass movements and how they differ: slides - CORRECT
ANSWER-shearing displacement between two masses along a surface or within a
thin zone of failure
Common types of mass movements and how they differ: slumps - CORRECT
ANSWER-rotational component, common in soils or rocks of low shear strength
Translational slide - CORRECT ANSWER-failure surface planar( most dangerous
condition is when planes of wet soil dip in the same direction as the slope)
Common types of mass movements and how they differ: lateral spread -
CORRECT ANSWER-slow to rapid lateral extensional movement of rock or soil
masses. Most result from liquefaction
Common types of mass movements and how they differ: flows - CORRECT
ANSWER-continuous internal deformation of the moving materal. may be viscous
or plastic
Safety Factor - CORRECT ANSWER-resisting forces/driving forces
Lithology - CORRECT ANSWER-most important compnent of slope stability
geologic materials of low strength - CORRECT ANSWER-clays
shales
certain volcanic tuff
