What types of tectonic activity form mountains?

If two tectonic plates plates push against each other, the earth's crust can fold and form fold mountains. Plate movement can also cause faults or cracks in the earth's crust. Some material can be pushed up and some rock material can be pushed down. In the end, the material piles up and form Fault-block mountains. Volcanic mountains form when volcanic ash and dried lava pile up. Almost like a cinder cone volcano, piles up more and more very time it erupts.
