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.
What Is Subduction? Subduction is a kind of geological recycling. It occurs at convergent tectonic plate boundaries or where two tectonic plates come crashing together, in slow motion of course. At a convergent boundary, two plates can come together and rise up into mountains.
