Chapter 10 Flashcards
Strain is:
A change in shape and/or volume of a rock caused by stress.
The three types of stresses are:
Compressional, tensional, and shearing.
Three types of strain are:
Elastic, ductile, and brittle.
A reverse fault is formed when:
The hanging wall is displaced upward along the fault plane.
An anticline is the product of:
Compressive stress
How do dip-slip and strike-slip faults differ from one another?
The describe different directions of movement along a fault plane.
A V outcrop pattern indicates:
A plunging fold.
Why does the formation of a fold require ductile behavior?
Because a rock must plastically deform around the bend.
What are strike and dip?
Symbols on a map indicating the orientation of a feature.
What types of faults are formed by tensional, compressive and shear stresses, respectively?
Normal fault, reverse fault, strike-slip fault.
Volcanic mountains are found at:
Plate boundaries and hot spots.
The Cascade range are:
A volcanic arc
Fault-block mtn systems are the product of:
Tensional stress
What is a fold-and-thrust belt?
A mtn belt at a continent-continent covergent margin.
