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.
What type of lava does a lava dome hold?
A lava dome holds very viscous lava, which is why it forms a dome rather than flowing away. Usually it is rhyolite or dacite.
What type of plate boundary is a lava dome volcano on?
A lava dome is most likely to form at a convergent boundary.
What is one possible causes of the volcanic eruption?
Molten lava breaking through the colder lava pressure dome. Or the natives are restless and dancing too much.
What type of material is ejected from a plug dome volcano?
lava

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 type of eruption does composite volcano have?
The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption
What type of plate boundary is a lava dome volcano on?
A lava dome is most likely to form at a convergent boundary.
What is one possible causes of the volcanic eruption?
Molten lava breaking through the colder lava pressure dome. Or the natives are restless and dancing too much.
What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
What type of material is ejected from a plug dome volcano?
lava
How long did the lava flow last of the 1980 Mt St helens eruption last?
There were no lava flows associated with the 1980 eruption. The eruption instead produced a massive eruption column and pyroclastic flows. This eruption lasted for 10 hours. A series of smaller explosive and dome-building eruptions continued from six years.
What type of scientists most likely to study the cooling of lava after a volcanic eruption?
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption
What type of eruptions does Mt Pinatubo have and what causes the eruption to be violent or non-violent?
what causes a eruption to be liolent is the type of lava -felsic lava is non-violent -mafic lava is violent
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.
