instances of word igneous is

commonly found in the surface and beneath the Earth, specifically in
divergent boundaries, convergent boundaries, subduction zones and
hotspots. Not all igneous rocks have the same physical and chemical
characteristics. They differ in the origin, process of formation, color,
density, size of grains, crystals and many more.
How are igneous rocks formed?
