There are different modes of eruption. Composite volcanoes are best known for explosive eruptions that send out plumes of ash, gas, and pumice. At other times they send out lava flows which may not resemble the typical conception of a lava flow. And still at other times a composite volcano can produce lava viscous enough that it builds into a dome rather than flowing away.
In very large explosive eruptions composite volcanoes can collapse in on themselves, forming a large crater called a caldera.
Occasionally, yes, but that is the exception rather than the rule. Most eruptions at shield volcanoes are effusive, but explosive phreatic eruptions, essentially steam explosions, can sometimes occur.
Stratovolcno are composed of ash and rock. Mount Fuji is an example of a stratovolcano. This type of volcano is also known as a composite volcano.
Yes. A composite volcano also known as a stratovolcano erupts quite a bit of ash and debris.
Yes they are and the layers as well , make up the ash and cinders. Ash and cinders also come out of the central vent.(:
Sometime along the line, they do.
slow erupt
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
Composite VolcanoesComposite Volcanoes. Composite volcanoes are tall, cone shaped mountains in which alternate layers of lava alternate with layers of ash. This happens when smooth lava flows alternate with explosive eruptions of lava fragments.
ash and lava
They can. Composite volcanoes vary in what they erupt. Many composite volcanoes are composed of a mixture of mafic, felsic, and intermediate rock. However, in most cases intermediated or felsic rock predominates.
Ash and Gas make composite volcanoes erupt i believe
No. Composite volcanoes erupt mostly ash and pumice.
Did you know that composite volcanoes make up 60% of the Earths volcanoes. Composite volcanoes don't always have to erupt from the top. They can have many magma chambers and can erupt from the sides. They can be made of basalt, rhyolite and/or andesite. They erupt both ash and lava. The lava is very thick. When the time comes for the volcano to erupt they start to become very quiet. (Sneaky eh?)
no
Yes. Composite volcanoes often produce violent eruptions.
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
ash
Composite volcanoes usually do not erupt mafic material. Intermediate material is the most common. The mafic material they do erupt is usually basalt.
No. Volcanoes also release ash and a variety of gasses.
Volcanoes with high levels of water in their lava produce ash, those with dry lava produce no ash.
composite means ''made of separate layers'' and a composite volcano is made of many layers of lava and ash. they are one of the most dangerous volcanoes , because they explode when they erupt. although, they are extremely quiet between eruptions. that's all i got, but i hope it helps!
they are made out of rock
