QUEENS UNIVERSITY GEOL 104 (ACTUAL 2025)
QUESTIONS AND VERIFIED ANSWERS.
Rayleigh waves
Greatest amplitude, shake up and down like an ocean wave.
Triangulation
Locating the epicentre using multiple seismographs located at
different stations.
Creep
Sloe gradual downslope movement of regolith on a slope.
Solifluction
Slow flow of saturated soil downslope indicating no frozen
ground is present in the moving layer.
Slumping
Slow moving rock that does not disintegrate but moves as a
coherent slump block. Slides along the FAILURE SURFACE
,Failure surface
The slope at which the mass slides along. Sometimes planar,
but are commonly curved.
Head scarp
The hanging wall that remains above the slump.
Toe
The end of the slump slope where debris piles up
Rock Slide
Sudden movement of rock down a non-vertical slope
Debris slide
Sudden movement of regolith down a non-vertical slope.
, Translational Slide
Slide moves along a planar surface.
Rotational
Falls along a curved surface, also known as a slump.
Slide
Movement of material as a coherent block.
Mudflow
A moving slurry of mud
Debris flow
A slurry consisting of mud and larger boulders.
Lamar
Mixture of volcanic ash and water
