Chapter 7 Vocab Flashcards
Fold in rocks that arches upward so older rocks are at the center
Anticline
Circular syncline that forms a depression in the ground
Basin
Stress that squeezes rocks together
Compression
Stress from the wright of material above buried rocks that does not allow the rocks to change shape
Confining stress
Change in the shape of rocks due to stress
Deformation
Fault in which the dip of the fault plan is inclined relative to the horizontal surface of earth
Dip-slip fault
Circular anticline that forms a mound on the ground
Dome
Fracture along which one side has moved relative to the other
Fault zone
Bend in rocks caused by compression
Fold
Block of rocks that is above a dip-slip fault plane
Hanging wall
Break in rocks along which there is no movement
Joint
Bend in rocks that causes them to be inclined relative to the horizontal
Monocline
Dip-slip fault in which the hanging wall drops down relative to the footwall
Normal fault
Dip-slip fault in which the hanging wall pushes up relative to the footwall
Reverse fault
Parallel stresses on rocks that push them past each other in opposite directions
Shear
Distance rocks move along a fault
Slip
Force per unit area on rocks
Stress
