What is a plug dome volcano?
when lava releases from the crater and becomes solid , shapes like a beam . we call it plug domes
The hole in the top of a volcano?
The top of a volcano may be a peak, lava dome, vent, crater, or caldera (empty magma chamber), depending on the state of the volcano. The top of any mountain can be called its summit.
What is an example of a dome volcano?
facts about dome volcanoes they are exctint
What type volcano is beacon rock?
Beacon Rock is not a volcano, but rather a volcanic plug. It was formed from the solidified magma that filled the vent of an ancient volcano.
How does a lava dome volcano work?
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 happens to the lava in the volcano?
Technically, it is not lava until it pours out of the volcano. While it is in the volcano it is still magma. What is not ejected in the form of lava might sink and form a plug, allowing the magma to once again build up in the volcano's magma chamber.

What will happen if the volcano has high vicosity magma but very low gas content?
The result will be a slow extrusion of lava which will either form a thick block lava flow or a lava dome. If the magma is too viscous it may fail to erupt and instead plug the volcano.
What are the release dates for Word World - 2007 To Plug a Volcano?
Word World - 2007 To Plug a Volcano was released on: USA: 2008
What will a rock do inside a volcano if it get hot?
It will plug up the volcano, which will usually keep the volcano from erupting for about 100 years. However, after that, the entire volcano itself will explode.

Is Olympus Mons on Mars a volcanic plug?
No. It is a volcano.
What mountain is the whangarei heads volcano?
Manaia is the remains of a volcano much of the volcano has eroded away leaving the volcanic plug which is what we call Manaia

Will a nuke set off a volcano?
Probably not. A volcano has a relatively large rock plug that would be very resistant to a nuclear blast. However, some volcanos that have a thinner plug, or a VERY big ground-penetrating nuke could possibly set off a volcano.
