Lava domes are generally composed of felsic, highly viscous lava, usually dacite or rhyolite.
A lava domes is a structure that forms when a volcano extrudes very viscous lava that builds into a dome-shaped pile rather than flow downhill.
Yes, a Dome volcano and a Lava Dome volcano are the same. A Dome volcano is characterized by the formation of a dome-shaped mound of lava that accumulates around the volcanic vent. Lava Domes are typically associated with eruptions of viscous lava that solidifies quickly, leading to the dome-like structure.
A lava dome holds very viscous lava, which is why it forms a dome rather than flowing away. Usually it is rhyolite or dacite.
Lava Dome Volcano
No. Mount St. Helens is a stratovolcano. There is a lava dome in the crater.
Not exactly. Some volcanoes do consist of simply a lava dome, but most lava domes are found in or on stratovolcanoes.
A volcano shaped like a dome.

When the lava ejected is too thick to flow, it solidifies near the vent and can form a dome-shaped feature called a lava dome. Lava domes are typically made of highly viscous lava, which does not flow easily. They can grow slowly over time as more lava is added to the dome from the eruption.
Lava domes usually consist of rhyolite or dacite lava.
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
its a volcanoe with a dome shape top it has bad eruptions.Dome volcanos are compsite volcanos which have a lava dome in them. The lava dome is created when moulten lava is pushed up from below at slow rates and when it hits the air it cools making a crust. These domes can continue to grow and become quite large.
