They actually form on the bottom of Earth's surface, since igneous(the word) is derived from molten magma
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
Such rock is extrusive igneous rock.
Igneous Rock
It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).

Igneous rock.
Igneous rock formed in the earths crust is known as intrusive rock. The magma that forms it cools slowly and therefore, creates rock with large crystals. An example of an intrusive igneous rock is granite.
Such rock is extrusive igneous rock.
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.
Intrusive igneous rock
Intrusive igneous rock (plutonic rock).
a Obsidion rock
Igneous rock that forms below the Earth's surface is intrusive.
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.
Igneous rock is formed when molten magma cools and solidifies within the Earth's crust. This process can happen either beneath the surface, leading to intrusive igneous rocks, or above the surface, resulting in extrusive igneous rocks like basalt.
