What types of rock forms at convergent plate boundary?
Mainly metamorphic, due the intense pressure. Some rocks will bend rather than break causing visible folds. Convergent plate boundaries can also produce igneous rocks from volcanic activity due to the subduction of the lighter crustal plate into the mantel which creates a tremendous amount of heat and pressure. Solidified magma may turn into granite. Magma which is blown out from a volcano may take the form of pumice, lava, obsidian, among others.
