What is the difference between stress and strain?
Which combination of conditions most favours ductile (rather than brittle) deformation?
Which structure does shear stress typically produce?
In an anticline, which rocks are exposed in the core after erosion?
A fault in which the hanging wall has moved up relative to the footwall, recording compression, is a:
What is the difference between the throw and the heave of a fault?
How does a joint differ from a fault?
In which type of unconformity do sedimentary rocks rest directly on eroded igneous or metamorphic basement?
Which sequence of events does an angular unconformity record, in the correct order (oldest first)?
True dip is the maximum slope of a bed measured at right angles to the strike. An apparent dip measured in any oblique direction is:
A bed dips at 30 degrees with a horizontal outcrop width of 40 m at right angles to strike on flat ground. Its true (perpendicular) thickness is closest to:
In a vertical borehole a bed dipping at 30 degrees is intersected over 20 m. Its true (perpendicular) thickness is closest to:
Using the rule of Vs, what does the V of an inclined bed's outcrop indicate where it crosses a valley?
Which principle tells you that an intrusion or fault is younger than the rocks it cuts?
