What igneous rocks form above the earths surface?

What groups of rocks can igneous rocks be formed from?
igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.
How and where are igneous rocks formed?
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
