There are two types of volcanoes formed by liquid rock (lava/magma), one being a shield volcano that are spread out over a large area but are not very tall because of the lava being mafic in nature (very liquid lava) such as the types of volcanoes that formed Hawaii, and the other being a composite volcano which is formed by felsic (thick) lava, making them steep and tall.
lava
A volcano is made of solid rock.
according to my science class, its igneous rock. igneous rock is formed when magma/lava cools. if it cools slowly, it is conglomerate (coarse-grained or heavily grained..chunky.) if it cools fastly, it is fine grained (smooth.) i hope this helps!
Molten rock that pours out of a volcano is called lava. Lava is the liquid rock that flows from a volcano during an eruption.
The melted rock coming from a volcano is called lava.
magma
Igneous rock... There are extrusive (formed on the exterior of a volcano by lava) and intrusive (formed on the inside of a volcano by magma).
A volcano rock is rock formed from ash or lava erupted from a volcano.
lava
The rock that can be formed on the Eyjafjallajökull volcano is andesite. Andesite is an intermediate volcanic rock that is created from the cooling and solidification of magma within the volcano. It is a common rock type associated with explosive eruptions.

Volcano
Volcanoes bring liquid rock (magma) to the surface, which may have heavier elements from the lower crust and mantle.
The rock formed by cooling a liquid rock after processing is called a crystal.
