Are generically called lavas but may be specifically basalts, ignimbrites, andesites phonolites etc.
i think the answer your looking for is igneous rock.....that is the type of rock you get after megma cools.....
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
Intrusive igneous rocks.
The term that refers to rocks produced when melted rock or magma from inside Earth cools or hardens on or below Earth's surface is "igneous rocks." Igneous rocks are formed through the solidification of molten material, either on the surface (extrusive igneous rocks) or beneath the surface (intrusive igneous rocks). Examples of igneous rocks include basalt, granite, and obsidian.
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.
a Obsidion rock

Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
extrusive- when melted rock material coools on earths surface instursive-when the melt cools below earths surface

when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
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).
Extrusive igneous rocks.
Such rock is extrusive igneous rock.
An igneous intrusion.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
Igneous rock. Extrusive igneous rock forms at or near the surface, intrusive igneous rock forms below the surface.
