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 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.
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.
Is lava dome volcanoes the most errupted?
No. Cinder cones are the most common variety.
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.
Is a shield volcano and a lava dome volcano the same?
No. A shield volcano is a large, broad sloping volcano that forms over a long period of time as successive low-viscosity basaltic lava flows build on top of one another. A lava dome is a smaller, steep-sloped structure that forms fairly quickly as very viscous lava (usually rhyolite or dacite) builds up, but is too viscous to flow away.
Is lava a kind of fossil?
Lava is the liquid rock that comes out of volcanoes.
What are all kinds of volcanoes?
The main types of volcanoes are stratovolcanoes (composite volcanoes), shield volcanoes, cinder cone volcanoes, and lava dome volcanoes. Stratovolcanoes have steep slopes due to the alternating layers of lava flows, ash, and other volcanic debris. Shield volcanoes have gentle slopes due to the low-viscosity lava flows. Cinder cone volcanoes are small and steep-sided, formed from explosive eruptions. Lava dome volcanoes are formed from slow, viscous lava flows piling up near the vent.
Do dome-shaped mountain's erupt?
Yes, dome-shaped mountains can erupt if they are volcanoes. The dome shape is typically formed by viscous lava accumulation during non-explosive eruptions, creating a gentle slope. While the eruptions may be less violent compared to stratovolcanoes, dome-shaped volcanoes can still release lava, ash, and gas.
What type of material is ejected from a plug dome volcano?
Plug dome volcanoes typically eject viscous magma, which is known as rhyolite lava. This lava is thick and flows slowly, leading to the formation of steep-sided domes as it cools and hardens. As a result, plug dome volcanoes tend to have explosive eruptions due to the high pressure build-up of gas within the viscous magma.
How tall can dome volcanoes get?
Dome volcanoes can vary in height, but typically they are shorter and more broad compared to other types of volcanoes. They can range from meters to hundreds of meters tall, depending on the amount of erupted lava and the duration of the eruption.
What kind of volcanoes are there?
There are four main types of volcanoes. These include shield volcanoes, cinder cones, composite volcanoes, and lava domes.
