FranAt a normal fault, the hanging wall moves downward relative to the footwall due to tensional forces. This type of faulting is typically associated with extensional tectonic settings where the Earth's crust is being pulled apart. Normal faults are characterized by steep dip angles and can lead to earthquakes.
Along a normal fault, the hanging wall moves down relative to the footwall. Normal faults usually form where tectonic plate motions cause tension. Tension is stress that pulls rocks apart. Therefore, normal faults are common at mid-ocean ridges. At mid-ocean ridges, plate separation causes oceanic lithosphere to break into fault blocks.

Is the San Andreas Fault a normal fault?
No, the San Andreas Fault is a strike-slip fault, not a normal fault.
Which type of fault is the result of tension forces?
A normal fault.
In normal fault what happens to the foot wall?
In a normal fault, the hanging wall moves down relative to the footwall. This results in the footwall being pushed up and becoming uplifted relative to the hanging wall.
Which type of fault cause a fault-block mountain to form?
A normal fault causes a fault-block mountain to form. In a normal fault, one block of rock moves downward relative to the other, creating a step-like feature. Over time, repeated movements along the fault can uplift and deform the crust, leading to the formation of fault-block mountains.
Is a thrust fault a normal fault?
No, a thrust fault is a type of reverse fault, where the hanging wall moves up and over the footwall. In contrast, a normal fault is a type of fault where the hanging wall moves down relative to the footwall.
