they form in three main places where lithospic plate pull apartat mid-ocean ridges,where plates come together and making it thicker amd allowing to melt,see more at About Volcanism.
igneous rocks that form on earth's surface
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Rhyolititcen rocks.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
igneous rocks form within earths surface
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
No, igneous rocks can form both beneath and above the Earth's surface. Intrusive igneous rocks form beneath the surface as magma cools and solidifies underground. Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava cools and solidifies quickly.
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.

Igneous rocks that form below the Earth's surface are called intrusive igneous rocks (or plutonic).
Igneous rocks form when molten rock (magma) reaches the Earth's surface and cools. It then becomes an igneous rock
