Lava domes usually consist of rhyolite or dacite lava.
Not exactly. Some volcanoes do consist of simply a lava dome, but most lava domes are found in or on stratovolcanoes.
The presence of a Lava dome is not really a good indication of danger. Many inactive volcanoes still have a lava dome. If a lava dome is present on an active volcano, and it is growing, it could signify a build up before an eruption.
Mt. Lassen is a lava dome type of volcano. The domes of lava dome volcanoes grows from within, and commonly occur within the craters or on the flanks of large composite volcanoes.
a broad-domed volcano is formed by lava flows. the amount of times the volcano has erupted effects how broad the dome would be, because when the lava flows it wears away the dome of the volcano.
No. Cinder cones are the most common variety.
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
Lava is the liquid rock that comes out of volcanoes.
The different shapes of volcanoes include composite volcanoes or stratovolcanoes with steep sides and symmetrical cones. Cinder cone volcanoes have a summit with a bowl shape crater. Shield volcanoes are low and flat. Lava dome volcanoes have a dome shape.
There are four main types of volcanoes. These include shield volcanoes, cinder cones, composite volcanoes, and lava domes.

Hot molten lava like everywhere else
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.
