If we wish our following sample that marble to deform plastically rather than as a brittle substance, we must conduct our next experiment at _________.lower temperatures and also lower confining pressureslower temperatures and greater confining pressureshigher temperatures and lower confining pressureshigher temperatures and greater confining pressuresWhich that the following conditions would favor folding rather than faulting?low temperatures and also low confining pressureslow temperatures and also high confining pressureshigh temperatures and also low confining pressureshigh temperatures and also high confining pressuresWhich variable does not affect whether urgently is major or gentlethe size of the used forceslength the time the force was appliedage the the absent unitsthe ability of the rocks to withstand deformationUpfolds or arcs of layered rock room called:anticlinesfaultssynclinesunconformitiesDownfolds or containers of layered rock space called:anticlinesfaultssynclinesunconformitiesA large circular or oval upward bulge of absent layers is referred to as a(n) _____anticlinesynclinebasindomeIf the sedimentary rocks on a geologic map form a zigzag pattern, the underlying framework probably consists of _________.horizontal anticlines and also synclinesplunging anticlines and synclinesdomes and also basinstrike on slide faults
The framework shown above is a(n) ________.anticlinesynclinebasindomeThe framework shown over is a(n) ________.horizontal and also symmetrichorizontal and also asymmetricplunging and also symmetricplunging and also asymmetricWhat form of fault is identified by the rocks above the fault airplane moving upward loved one to the rocks listed below the fault plane?normalstrike slipreverseall that theseA fault plane strikes north-south and also dips steeply come the west. Geologic observations show that many of the fault motion was vertical and also that Mesozoic rocks occur eastern of the fault and also Paleozoic rocks happen west of the fault. What type of error is this?normala appropriate lateral win slipreverseall that theseWhat type of error is characterized by movement both follow me strike and also along dip?oblique-slipstrike slipreversenormalAn oblique-slip fault suggests _______tensional pressures onlycompressive pressures onlyshear pressures onlyshear forces combined with compressive or tensional forcesStrike-slip faults ________.have mostly horizontal movement have primarily vertical movementhave no appreciable displacementare low angle reverse faultsWhich 2 measurements define the orientation the a fault aircraft at a offered location?axis and planestrike and also diplateral and also thrusttrend and plungeDip-slip faults are associated with ________ forces.shearingtensionalcompressivetensional and also compressiveWhat kind of error is a thrust fault?low-angle common faultlow-angle reverse faulthigh-angle reverse faultlow-angle strike-slip faultOverthrusts are brought about by massive _______ forces.
