What is the difference between the forces that could explain fault block mountains and the forces that could account for an orogeny?

Fault block mountains are formed by the uplifting and tilting of large blocks of the Earth's crust along fault lines, usually due to tensional forces pulling the blocks apart. Orogeny, on the other hand, refers to the process of mountain building typically caused by the collision of tectonic plates, resulting in the folding, faulting, and uplifting of rock layers. The forces generating orogeny are compressional, as opposed to the tensional forces that create fault block mountains.
