Rhyolite is an igneous rock that has formed from rapidly cooling lava or ash.
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
Igneous Rock.
The sedimentary rocks would have to melt and cool again to make an igneous rock.

Old, cool igneous rock sinks.
the structure of an igneous rock is metamorphic rock that has been heated rapidly and turned into magma then cooled to create igneous rock its gay
Extrusive igneous rock.
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
It becomes a Igneous rock.
It's called extrusive igneous rock--rapidly solidified lava.
Igneous rocks are made by melted rock materials that cool and harden.Which the answer would be there formed that way and no other rock is formed that way.
A metamorphic rock can melt into magma and then cool and crystallize to become an igneous rock. Or, a sedimentary rock (or sediments) can melt into magma and then cool and crystallize to become an igneous rock. Also, an igneous rock itself can undergo this process of melting and cooling as well.
The answer is pitchstone. it is and igneous rock.
