When rocks are put under great pressure, the may crack or fracture. one section of rock may then slide alongside or over another
-this fracture is called a fault
faulting causes large blocks of the Earth's crust to drop down relative to other blocks
Faulting is caused by the movement of Earth's tectonic plates, which can create stress along plate boundaries. When this stress exceeds the strength of the rocks in the Earth's crust, it can result in the formation of faults, where rocks break and move relative to each other. This movement can lead to earthquakes and the deformation of the Earth's crust.
It is the deformation of the Earth's crust by such geologic processes as volcanism, faulting, and folding.

Folding and faulting are caused by tectonic forces within the Earth's crust, primarily due to the movement of large plates that make up the Earth's surface. Folding occurs when rock layers are compressed and bent, while faulting happens when rocks break and slide along fractures in the Earth's crust.
What happens during faulting is that there is some kind of sudden pressure put on a section of crust. This causes it to break or crack, causing a fault.
An upfold on the crust caused by faulting is called an anticline. It is a geologic structure where rock layers are folded upward in an arch-like shape. Anticlines are typically associated with compression forces in the Earth's crust.
Do you mean 'diastrophism'. If so, it refers to the deformation of the Earth's crust, especially folding and faulting
Compression causes rocks to be pushed together, leading to folding and faulting in the crust, often resulting in mountain building. Tension, on the other hand, causes rocks to be pulled apart, resulting in the formation of rift valleys and normal faulting. Both compression and tension are important in shaping the Earth's crust and can lead to the formation of various geological features.
Compression and tension can indeed affect the thickness of the Earth's crust. Compression can thicken the crust by folding and faulting, while tension can cause stretching and thinning of the crust through processes like rifting and faulting. These tectonic forces play a significant role in shaping the Earth's crust over geological time scales.
At the region between the two plates, called a transform boundary, pent-up energy builds in the rock. A fault line, a break in the Earth's crust where blocks of crust are moving in different directions, will form. Most, though not all, earthquakes happen along transform boundary fault lines.
