Igneous landforms can usually be placed in one of two camps: Intrusive and Extrusive. Intrusive forms result from magma solidifying beneath the earth's crust, then later exposed by earthquake, erosion, glacial activity, etc.gneous forms seen in canyons are usually intrusives; the magma crystallized beneath the earth's crust but has since been exposed by whatever formed the canyon. Some igneous forms in canyons are extrusive, such as the lava flow in the western portion of Grand Canyon NP; the lava flowed after the canyon had been formed.
