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.
-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.
Fault-block mountains
Mountains are most often formed on faults. Because these faults occur due to the space between tectonic plates, these faults take the form of lines. Thus, the thin belts are along these long lines.
At a divergent boundary, faults known as normal faults occur. These faults form as tectonic plates move away from each other, leading to the stretching and thinning of the Earth's crust. This results in the upper plate sliding down along the fault plane relative to the lower plate.
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.

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.
along nearly parallel 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.
Rocks moving apart can cause normal faults to form, as opposed to reverse and strike-slip faults.
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.
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.
