Answer Text:
Faulting
Faulting is the cracking/fracturing of the brittle crustal rocks due to tectonic forces. Faults are fractures or cracks that develop in the crust.
• When tensional forces cause crustal rocks to stretch and fracture at the region of maximum tension.
• When compressional causes squeezing of crustal rocks to fracture at the areas where they are intensely squeezed.
• When vertical movements exert pressure on rocks leading to fracturing.
• When shear forces cause crustal rocks to tear.

Parts of a Fault
1. Upthrow-part of the land displaced upwards.
2. Down-throw-part of the land displaced downwards.
3. Throw-vertical displacement.
4. Heave-horizontal displacement
5. Hade-inclination of fault to vertical plane
6. Fault line-fault path
7. Fault plane-separation of land created by the fault
