Addendum: Differentiation of magma (fractional crystallization) also plays a big role in creating felsic magmas from mafic magmas. Also, granite can form at convergent boundaries that involve continental crust only (e.g., Indian and Asian plates).
Divergent boundaries are boundaries where plates pull away from each other, forming mild earthquakes and volcanoes as magma comes to the surface. Convergent boundaries are boundaries where two plates are pushing into each other.his happens at a convergent boundary. A convergent boundary is a boundary where two separate plates are pushing into each other. There are two kinds of surface features that are associated with a convergent boundary. The first is a deep ocean trench that forms a line of the two colliding plates.
