Late penalty: 1 point/day

__a,c,g_____are hanging/head walls

__b,d,h_____ are foot walls

__M,O_____are caused by shearing

__N,L______are caused by compression’

___K______are caused by tension

__N,L_____are/is a reverse fault

__N_______are/is a thrust fault

__M______is a right-lateral strike slip fault

__O_______is a left-lateral strike slip fault

__N,L______would be more common at convergent plate boundaries

__K______ would be more common at divergent plate boundaries

__O,M___ would be more common at transform plate boundaries

2. Match the following drawn diagrams of faults with the corresponding names of the fault, plate boundaries and corresponding type of stress.

Name of fault	Sketch	Type of stress that causes it	Name of Plate boundary where is it most common
Reverse/thrust faults	SHAPE \* MERGEFORMAT	Compression	C-C convergent O-O and O-C convergent
Strike-slip(or transform) faults	SHAPE \* MERGEFORMAT	Sharing	Transform(o-o and c-c)
Normal faults	SHAPE \* MERGEFORMAT	Tension (extension)	c-c divergent o-o divergent
