The force within the Earth that causes rocks on either side of faults to push in opposite directions is called tectonic stress. This stress is caused by the movement of Earth's tectonic plates, leading to compression, tension, or shear forces along fault lines.
In a strike-slip fault, rocks on opposite sides move horizontally past each other in opposite directions or at different rates. This type of fault is categorized as either left-lateral or right-lateral based on the direction of movement when facing the fault.
Normal faults are characterized by the hanging wall moving down relative to the footwall, while reverse faults are characterized by the hanging wall moving up relative to the footwall. Both faults are caused by compressional forces in the Earth's crust, but their movements are opposite in direction.
Strike-slip faults are caused by horizontal shear stress along the fault plane, which results in horizontal movement of the rocks on either side of the fault. The movement can be either left-lateral (sinistral) or right-lateral (dextral), depending on the direction of the shear stress.
At normal faults, the main direction of stress is extensional, with the hanging wall moving down relative to the footwall. At reverse faults, the main direction of stress is compressional, with the hanging wall moving up relative to the footwall. In strike-slip faults, the main direction of stress is horizontal, with the blocks of rock sliding past each other horizontally.
Transform boundaries produce strike-slip faults. These boundaries occur where two tectonic plates slide horizontally past each other in opposite directions. The movement can be either right-lateral or left-lateral, producing different types of strike-slip faults.

Strike- Slip Faults
In a strike-slip fault, rocks on opposite sides move horizontally past each other in opposite directions or at different rates. This type of fault is categorized as either left-lateral or right-lateral based on the direction of movement when facing the fault.
When rocks on opposite sides of a fault move in the same direction at different rates, it results in a strike-slip fault. This type of fault occurs when there is horizontal motion along the fault line. The two main types of strike-slip faults are left-lateral and right-lateral, depending on the direction of movement when facing the fault.
Transform boundaries like the one on the California cost cause strike slip faults. As the two plates move in opposite direction the earthquake occurs.
Normal faults are characterized by the hanging wall moving down relative to the footwall, while reverse faults are characterized by the hanging wall moving up relative to the footwall. Both faults are caused by compressional forces in the Earth's crust, but their movements are opposite in direction.
The main direction of the stress on blocks of rock at normal faults, reverse faults and the strike slip faults usually happens at the weak areas.
Strike-slip faults are caused by horizontal shear stress along the fault plane, which results in horizontal movement of the rocks on either side of the fault. The movement can be either left-lateral (sinistral) or right-lateral (dextral), depending on the direction of the shear stress.
Tectonic plates
That causes earthquakes
In science, fault refers to a fracture or zone of fractures in Earth's crust where rock on either side has moved relative to the other. It is typically associated with tectonic plate movement and can lead to earthquakes. Faults are classified based on the direction of movement, such as normal faults, reverse faults, and strike-slip faults.
At normal faults, the main direction of stress is extensional, with the hanging wall moving down relative to the footwall. At reverse faults, the main direction of stress is compressional, with the hanging wall moving up relative to the footwall. In strike-slip faults, the main direction of stress is horizontal, with the blocks of rock sliding past each other horizontally.
