Well the tectonic plates move, and there are different names for how they move. Also the mountains may be made from volcanic activity. Anyways the processes are: Faulting, Folding, and also the thrust and reverse movement of the plates.
The processes that lead to the formation of mountain ranges are collectively known as orogeny. This includes tectonic plate movement, volcanic activity, faulting and folding, and erosion, all contributing to the creation and shaping of mountains. Notably, mountains can form from the collision of continental plates or from volcanic eruptions.
