Lesson on Faulting and Parts of a Fault
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
