Intermediate magma is also known as andesitic magmas and these are created when an oceanic plate subducts beneath a continental plate. The magma is generated in the wedge of mantle rock beneath the crust. The Cascade Mountain Range is formed due to the subduction of the Juan de Fuca Plate beneath the North American Plate.
