Transform fault boundary
Convergent boundary
Divergent boundary
Reverse fault
In these faults, blocks of rock move sideways on either side of the fault plane (no vertical motion)
Reverse faults
Convergent boundary
Normal faults
Strike-slip faults
Volcanoes having alternate layers of lava & ash, have repeated explosive & non-explosive eruptions
Composite volcano
Shield volcano
Mid-ocean ridge
Cinder cone volcano
In these faults, the block of rock above the fault plane (the hanging wall) slides down relative to the other block (the foot wall)
Normal fault
Reverse fault
Backwards fault
Strike-slip fault
Along these faults, the block of rock above the fault plane (hanging wall) moves up relative to the other block (foot wall)
Reverse fault
Normal fault
Upside down fault
Strike-slip fault
