Answer 20

footwall (block)
hanging wall (block)

Question 21

is the rock that is placed
on top of the fault.

Question 23

moves in a fault

Answer 23

footwall block

Question 24

does not move in a fault

Answer 24

hanging wall block

Question 25

types of fault

Answer 25

Normal Fault Reverse Fault Strike-Slip Fault

Question 26

A rock is pulled apart by tension in Earth’s crust. Rock drops down as it breaks.

Answer 26

normal fault

Question 27

Rock is forced upward as it is squeezed by compressional stress. A continental plate colliding with another continental plate

Answer 27

reverse fault

Question 28

Rock is sheared (or cut) from sheer stress. Rocks on each side of the fault slip past each other as they break.

Answer 28

strike-slip fault
