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
2. The Land Between Two Normal Faults Moves Upward To Form What?
is a Fault - Block Mountain.

What is the rock age of the normal fault?
The rock age of a normal fault can be determined by analyzing the age of the rocks on either side of the fault. Normal faults typically form in response to extensional forces, where older rocks are uplifted and younger rocks are deposited in the hanging wall. By dating the rocks on either side of the fault, geologists can determine the relative timing of fault movement.
What are the movements produced by the three types of faults?
-Normal Faults form when the hanging wall moves down. -Reverse Faults form when the hanging wall moves up. -Strike-Slip Faults have walls that moce sideways, instead of up or down.
When rocks are pulled apart because of tension these faults often form?
When rocks are pulled apart due to tension, normal faults typically form. In these faults, the hanging wall moves downward relative to the footwall, resulting from the extensional forces acting on the crust. This type of faulting is commonly associated with divergent plate boundaries, where tectonic plates are moving away from each other. As a result, normal faults can lead to the formation of rift valleys and other geological features.
Which mountains form at large-scale normal faults where the footwall and hanging wall spread apart from each other?
Fault-block mountains
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.
Fault-block mountains form when large blocks of crust are and tilted along normal faults.?
Fault-block mountains are created when tensional forces cause large blocks of the Earth's crust to be uplifted along normal faults, resulting in steep escarpments and flat valleys. Over time, erosion can modify their shape and create distinctive landscapes.
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
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.
Fault-block mountains form when large blocks of crust are and tilted along normal faults?
Fault-block mountains are created due to the movement of tectonic plates along normal faults. As the block of crust is uplifted, the surrounding material erodes, leaving a narrow mountain range with steep slopes on one side and a gentler slope on the other. Examples of fault-block mountains include the Sierra Nevada in California and the Tetons in Wyoming.
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 is the rock age of the normal fault?
The rock age of a normal fault can be determined by analyzing the age of the rocks on either side of the fault. Normal faults typically form in response to extensional forces, where older rocks are uplifted and younger rocks are deposited in the hanging wall. By dating the rocks on either side of the fault, geologists can determine the relative timing of fault movement.
