fault block
The energy released by fault movement forms seismic waves.
A fault-block mountain forms where the edges of two plates come together to create a fault. When one plate pushes up over the other one, the upper one can continue up until it is high enough to create a fault-block mountain.

The type of mountain that forms when forces pull from opposite directions is the fault-block mountain.
The crack that forms when rocks break and move past each other is called a fault . The blocks of rock that are on either side of the fault are called fault blocks .

A fault-block mountain forms when tectonic forces cause blocks of the Earth's crust to be uplifted along faults. As the blocks are uplifted, erosion wears down the surrounding rock, leaving steep, rugged mountain peaks. Over time, these mountains can continue to rise as a result of ongoing tectonic activity.
The movement of Earth's crust forms metamorphic rock when existing rocks are subjected to high pressure, temperature, or chemically active fluids. These conditions cause the rock to recrystallize, resulting in new mineral compositions and textures without fully melting. Metamorphic rocks are typically found in regions of tectonic activity, such as along fault lines or mountain ranges.
The block of rock below the fault line is called the footwall. This block remains stationary while the other block, called the hanging wall, moves during fault movement.
The 4 main types of fault are summarised below:Dip-slip faultsStrike-slip / transcurrent faultsOblique-slip faultsListric faultDip slip faults are those where the relative motion on the fault is broadly vertical. Examples include normal faults where the hanging wall moves down relative to the foot wall. Reverse faults have the opposite sense of motion, with the hangingwall moving up relative to the footwall. Thrust faults are a special type of reverse fault where the dip of the fault plane is at a shallower angle than 45 degrees from the horizontal.Strike slip or transcurrent faults are those where the relative motion on the fault is broadly horizontal. The fault plane in these types of faults is normally near vertical and the sense of motion is described in terms of the relative movement of the rockmass on the far side of the fault plane. If this relative movement is to the left, then it is known as a sinistral fault. If he motion is to the right it is a dextral fault.Oblique slip faults are those have have a significant component of both vertical and horizontal movement. They can be thought of a composite of the dip slip and strike slip faults.Listric faults are characterised by a curved fault plane surface. They usually start of relatively steep and then become more shallow with increased depth and may ultimately become horizontal.Previous Answer:The four different types of faults are normal, reverse, transcurrent (also known as strike-slip), and thrust. Normal faults are so named because movement follows what would be expected from normal effects of gravity--one plate slides downward, pulled by gravity, and the other plate forms a cliff face. The reverse fault, then, is the opposite of a normal fault--one plate moves against gravity and slides over the other. Transcurrent faults feature horizontal movement rather than up/down movement; plates slide along each other, resulting in offset roads and such. Finally, thrust faults are similar to reverse faults--one plate moves over the other--but the angles of movement for thrust faults are generally less steep, and thrust faults are more commonly associated with geographical features such as mountain ranges.
