About Igneous rockHide

Name:
for the Latin word Ignis, meaning fire
A rock that has solidified from a molten state, but may include some formed from related cumulate, deuteric, metasomatic or metamorphic processes. Rock formed by the solidification of molten material that originated within the earth or extraterrestrial bodies.
