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!
ummm volcanic rock? but really its black rock and its all over near the hawaiian volcanoes! :)
A cone-shaped mountain formed from rock thrown up from inside the Earth is called a volcano.
The molten rock that is found inside the earth is usually simply called magma. It becomes lava after it leaves the volcano at the surface of the earth.
Outside the volcano is rock. inside the volcano is rock, and, in an active volcano, magma (known is lava when it reaches the surface) hope this helps! poopmonkey love u
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.

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.

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.

When you have a volcano the molten rock is called Magma when it is inside the volcano but when it gets out of the volcano it changes name to Lava.
Outside the volcano is rock. inside the volcano is rock, and, in an active volcano, magma (known is lava when it reaches the surface) hope this helps! poopmonkey love u
A volcanic neck is an eroded remnant of a pipe that once fed a volcano. It is formed when magma solidifies inside the volcano's vent and the surrounding softer rock erodes away, leaving behind a tall column of volcanic rock.
