Answer: Heidi Doody. Heidi Doody was built by Margo Rose and had the voice of Norma MacMillan and Donna Miller. Heidi was introduced as a stranger who saved Buffalo Bob's life in Africa. Later, Heidi was adopted and became Howdy's sister.
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.
most metamorphic rocks produced during this type of metamorphism that is in association with mountain building; large segments of earth's crust are intensely deformed along convergent plate boundaries; occurs where oceanic lithosphere is subducted to produce continental volcanic arcs; high temperatures and pressures.ubduction Zone Metamorphism. rocks and sediment carried to great depths along convergent boundaries where oceanic lithosphere is subducted under continental crust; differs from burial because differential stress plays a major role in deforming rock; high pressure, low temperatures.
