When compression pushes rocks together, faults form when the stress exceeds the strength of the rocks, causing them to break and push against each other. These fault zones can be areas of high seismic activity as the rocks continue to be pushed and undergo deformation.
The rocks on opposite sides of a fault that move in opposite directions or in the same direction at different rates are called fault blocks. These blocks can move horizontally, vertically, or rotationally along the fault line.
In a strike-slip fault, rocks on opposite sides move horizontally past each other in opposite directions or at different rates. This movement is caused by shear stress and can result in earthquakes. This type of fault boundary is commonly found along transform plate boundaries.
These types of rocks are known as "fault rocks" or "fault gouge." The movement of rocks on opposite sides of a fault can create various structures such as slickensides, cataclasite, or mylonite, depending on the amount of movement and deformation that has occurred.
Shear stress pushes rocks in two different directions, causing them to slide or deform along parallel planes. This type of stress is common along fault lines where tectonic plates are moving past each other.
A normal fault is the opposite of a reverse fault.
A reverse fault is caused by compressional forces in the Earth's crust, where rocks are pushed together, causing the overlying rock to move up and over the underlying rock along the fault plane. This results in a reverse fault where the hanging wall moves vertically upward in relation to the footwall.
When rocks on opposite sides of a fault move in opposite directions, it is called a strike-slip fault. When they move in the same direction, it is called a normal or reverse fault, depending on the type of stress causing the movement. The rate of movement can vary from slow creep to sudden jolts during an earthquake.

When compression pushes rocks together, it creates a reverse fault. In a reverse fault, the hanging wall moves up relative to the footwall due to compression forces pushing the rocks together.

Tensile stress is the result of a force acting over a cross sectional area that pulls material apart. This occurs in normal faults, rift valleys and at divergent plate boundaries.
