I don't know about viscous, but a lava dome is a steep-sided dome of thick lava extruding from a volcanic vent.
a viscous lava dome is when the lava from the volcano contains alot of silica. Viscous=sticky. So the lava cools quickly of the sides of the volcano. And often a viscous lava dome volcano is explosive.

∙ 10y agoThere are two types of volcanic domes. First, there are lava domes. A lava dome forms when extremely viscous lava is solwly extruded from the ground, but is too viscous to flow away. The second type is a cryptodome. These form when magma gathers ast a shallow depth and essentially inflates that ground above it.

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 is an example of a dome volcano?
facts about dome volcanoes they are exctint
What is Novarupta?
Novarupta is a new volcano that emerged on the Alaska Pensinsula in 1912. During its initial phase of activity, Novarupta produced the largest volcanic eruption of the twentieth century, forming a caldera and later a lava dome.
Is a volcanic dome non explosive?
Sometimes they are and sometimes they are not. The processes that form volcanic domes are non-explosive, but they can produce explosive eruptions. There are two different types of volcanic dome. The first is a lava dome. These form when very viscous lava is extruded onto the surface. Normally, highly viscous magma is gas-rich, and it is this gas that drives an explosive eruption. The formation of a lava dome can potentially mean two different things. In some cases a lava dome is a sign that a volcano is running out of gas and no longer has the potential to explode in the near future. In other cases a dome may just be the tip of a larger body of magma. The gas in this tip has escaped, allowing it to flow out and form a plug to the gas-rich magma beneath it. Pressure can built beneath this plug until the remained of the magma erupts explosively. The second type is a cryptodome. A cryptodome forms forms when viscous magma collects at a shallow depth beneath the surface and essentially inflates the ground above it. This in and of itself is not an explosive process, but can readily lead to an explosive eruption.
What is volcanic tuft made from?
The correct spelling is volcanic tuff instead of volcanic tuft. Volcanic ash that has been ejected from vents during eruption makes volcanic tuff.
How are dome mountains different from volcanic mountains?
1 difference is that the dome mt. sleeps and the volcanic doesn't
How are dome shaped mountains formed?
Volcanic Activity
What are three features formed by magma?
A batholith, a volcanic neck, and a dome mountain.
What are the four main volcanic forms?
* Cinder Cone * Composite * Shield * Lava Dome
What are the four kind of mountains?
They are the fold mountain, the fault mountain, the dome mountain, and the volcanic mountain.
What are the four types of mountain?
fault block mountains, volcanic mountains, fold mountains, dome mountains
What are the three types of non-boundary mountains?
The three types of non-boundary mountains are volcanic mountains, dome mountains, and fault-block mountains. Volcanic mountains form from volcanic activity, dome mountains are created by the uplifting of large blocks of crust, and fault-block mountains are formed when large crustal blocks are uplifted along faults.
Which is a rounded volcanic feature that forms when a mass of thick lava slowly erupts from the vent?
This is called a lava dome.
What does a dome mountain look like?
A dome mountain is a type of mountain with a rounded or domed shape, usually formed by volcanic activity. It lacks the sharp, pointed peaks commonly associated with other mountain types. Examples include Half Dome in Yosemite National Park in the United States.
What are five landform features formed by magma?
volcanic neck, dike, sill, batholiths, dome mountain, and laccolith
What are four types of mountain building?
When studying Earth Science or Mountains it is important to know the different types of mountain building. These are volcanic, fold, block and dome.
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.
