Normal Fault
- in a normal fault, the hanging wall slips down relative to the footwall
- footwall- the rock that lies below
- hanging wall- the block of rock that lies above
- normal fault- tension in Earth's crust pulls rock apart which causes normal fault

How can faulting act as a construction force?
Rock moves upward along faults to form a mountain range.
How does a normal fault change the surface?
normal faults cause mountains to form
What group of minerals form along faults?
vein minerals form between faults.
Why do normal faults form?
because of the ductile behavior of rock
What are the three types of plate motion and the faults that are characteristic of each motion?
convergent plates produce thrust faults divergent plates form normal faults transform plates form strike/slip faults
Is the fault-block created by two reverse faults?
No, a fault-block is not typically created by two reverse faults. Reverse faults involve the upward movement of rock layers, and when two reverse faults occur in close proximity, they can create a complex structure but do not directly form a fault-block. Fault-blocks are more commonly associated with normal faults, where blocks of the Earth's crust are pulled apart, resulting in sections that drop down relative to others. In summary, while reverse faults can influence the landscape, they do not create fault-blocks in the same manner as normal faults do.
What is the name given to a valley formed between two faults?
The valley that forms between two normal faults is known as a graben structure. This may develop further into a rift valley and ultimately form a new mid ocean ridge.
How do faullt-block mountains form?
along nearly parallel normal faults.
What is created when rocks move apart?
Rocks moving apart can cause normal faults to form, as opposed to reverse and strike-slip faults.
Do normal faults result in crustal shortening?
No, normal faults result in crustal extension, not shortening. Normal faults form as a result of tensional stresses that stretch the Earth's crust, causing one block of rock to move downward relative to the other block. Crustal shortening is typically associated with reverse faults or thrust faults, where compressional stresses push rocks together, shortening the crust.
What are some connections between plate boundaries forces and faults?
Plate boundaries experience different types of forces, such as compression, tension, and shear, which can cause faults to form. In compression zones, faults like reverse and thrust faults can develop due to the plates being pushed together. In tension zones, normal faults form as plates are pulled apart. Shear forces along transform boundaries can create strike-slip faults.
