Dome mountains are formed exactly the same way as VolcanoesThe inside of the earth can get so hot that rock slowly melt and become magma. Magma is much lighter then the hard solid rock that surrounds it, this causes it to rise and collect in chambers in the earth. though the magma cools before a volcano is formed. (hope this helps)

Why are lava domes such potentially dangerous volcanoes?
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.
Why did the Lassen peak volcano erupt?
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.
What are the broad slightly dome-shaped volcanoes called?
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.
What are the 4 types of volcanoes which exist and what type of lava do they produce?
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.
What are the different shapes 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.
Is lava dome a type of volcano?
Not exactly. Some volcanoes do consist of simply a lava dome, but most lava domes are found in or on stratovolcanoes.

What kind of lava do lava dome volcanoes contain?
Lava domes usually consist of rhyolite or dacite lava.

Is lava dome volcanoes the most errupted?
No. Cinder cones are the most common variety.

Which is fomed by fast cooling lava--pumice granite or basalt?
Pumice is the result of extremely fast cooling lava.
Why is a lava dome called a lava dome?
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.
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
Can lava make volcanoes?
NO, volcanoes make lava.
