In most cases a lava dome is not a kind of volcano, but a structure that forms on a volcano. A key factor in how lava domes form depends on viscosity, which is how much a liquid resists flowing. For example, maple syrup is more viscous than water. Lava varies in viscosity as well depending on its composition. Lava domes are formed from extremely viscous lava. This lava is so viscous that instead of flowing away from the source it simply piles up. The formation of a lava dome can be a sign of two things. The sort of magma (underground molten rock) that forms domes is usually rich in gas dissolved under immense pressure. The stuff that goes into the dome itself has lost that gas. In some gases the formation of a dome means a volcano is running out of gas and. at least for the time being, losing the ability to erupt explosively. In other cases the dome is just a plug for a larger, gas rich mass of magma. When the dome fails it is like opening a can of soda that has been shaken, only much more violent. The gas, suddenly under lower pressure, comes out of solution, forming rapidly expanding bubbles that produce a large explosion.
What else can I help you with?
Is a Dome volcano the same as a Lava Dome volcano?
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.
Is a dome volcano the same as a cone volcano. if not - what is a dome volcano?
a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.
What is the length and height of the dome volcano?

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.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
What volcano has a rounded dome?
Lava Dome Volcano

What is lava dome volcano?
A volcano shaped like a dome.
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.

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.
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 forms inside the crater of a volcano?
lava dome
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
What type of plate boundary is a lava dome volcano on?
A lava dome volcano is typically found at convergent plate boundaries, where two tectonic plates are colliding. The magma from the volcano is usually thick and sticky, causing it to build up and form a dome-shaped structure.
What is a lava dome volcano?
Lava starts building up underneath some surface (solid) materials. It is being pushed up by some underground forces. The upward pressure causes a dome like cap covering the 'liquid' lava. Eventually the lava breaks through and you have a volcanic eruption.
