The descending of rock layers at subduction zones causes metamorphism in two ways; the shearing effect of the plates sliding past each other causes the rocks coming in contact with the descending rocks to change. Some of the descending rock will melt because of this friction.
Regional metamorphism occurs due to the change in pressure and  temperature over a large region of the crust. It is the result of  high pressure and elevated temperatures th â¦ at are associated with  deep burial in an organic belt.Answered.egional metamorphism is a widespread precess involving both heat and directed pressure, and is involved in things like mountain building and activity deep with in the core.
