Quiz 1-Geological Structures_Sem2-2021/2022

Most folding of rock layers results from:

• shear stress

• compression

• tension

• fracturing

Rock is characterized as ductile:

• fracture easily when compression

• are found along the crests of anticlines

• show a great amount of plastic strain

• fracture easily when compression

A fault along which the hanging wall block moved down relative to the footwall block is a normal fault.

• True

• False

A structural basin is a(n):

• fault on which the hanging wall block moved down

• elongate fold with all strata dipping away from the fold axis

• kind of fracturing that occurs in lava as it cools

• oval fold with the youngest exposed rocks at its center
