Question

Quizplus · Accepted Answer

Intense squeezing from tectonic forces is not an environment in which an igneous rock forms. Igneous rocks form from the cooling and solidification of magma or lava. Explosive eruptions of volcanic ash can also form igneous rock if the ash particles are welded together. Solidification of magma at depth can form intrusive igneous rock, while cooling and solidification of lava can form extrusive igneous rock.
