An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...
An explosive volcano will form rocks such as scoria, pumice, and tuff.
The type of rock that you would expect to form as the result of an explosive eruption is Pumice.
Batholith rock.
the answer is igneous rocks...
volcanic (extrusive) igneous rock.
Igneous Rock.
It would have to be a volcano rock because the heat and magma hardens it and make it into a igneous rock. So when the volcano explodes it explodes with the magma. So when the magma heats and hardens it transforms into an Igneous rock.
Igneous rock is formed from magma.Magma goes out of the volcano, dries and creates igneous rock.
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
ummm volcanic rock? but really its black rock and its all over near the hawaiian volcanoes! :)
When a volcano erupts the molten cools quickly it is also known as volcano glass
Underwater volcano
A volcano rock is rock formed from ash or lava erupted from a volcano.

Igneous rock is formed from magma.Magma goes out of the volcano, dries and creates igneous rock.
The rock that is formed is an igneous rock. It's formed when the magma aka lava cools down it turns into a rock which is an igneous rock.
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).
igneous rock is formed when magma cools from a volcano
