Are generically called lavas but may be specifically basalts, ignimbrites, andesites phonolites etc.
Such rock is extrusive igneous rock.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.

An igneous intrusion.

a Obsidion rock
i think the answer your looking for is igneous rock.....that is the type of rock you get after megma cools.....
Ido what the answer is i looked it up and NOTHING
Intrusive igneous rock.
through volcanoes, lava comes out and when it cools it turns into igneous rock.

Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
