Composite volcanoes can contain a wide variaty of magmas ranging from basaltic to rhyolitic.
What else can I help you with?
What are the 4 classifications of volcanic eruptions?
Volcanoes can be active or inactive. When a volcano is active there is magma or lava moving around getting ready to make an explosion. When a volcano is inactive there is either rocks and bits of other stuff melting in the main vent making magma getting ready to become active or they are not doing anything, just sitting there like a mountain. The four main types of volcanoes are shield volcanoes, composite volcanoes, also called stratovolcanoes, cinder cones, and lava domes. Composite volcanoes are the most abundant, and an example is Mount Fuji in Japan. These volcanoes are formed from layers of ash. In contrast, shield volcanoes are gently sloping volcanic mountains built almost fully of lava flows. They were named on account of their shape , which is reminiscent of an ancient warrior's shield. These volcanoes are typically much larger then composite volcanoes. Lava domes and Cinder cones are much smaller than shield or composite volcanoes.Thats what some of the Volcanoes are!
Do composite volcanoes erupt ash?
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.
Why do composite volcanoes usaully produce violent eruptions?
They feature magma with very high viscosity
How a volcanoes opening affects eruptions?
Well, it could make the crater bigger. Or make it bigger. Or cause a caldera (a crater with collapsed walls)
Are hawaiian volcanoes low or high in viscosity?
Hawaiian volcanoes are typically low in viscosity, meaning they have a relatively fluid lava composition compared to other types of volcanoes. This low viscosity allows the lava to flow more easily, resulting in gentle eruptions characterized by flowing lava streams rather than explosive eruptions.
What makes composite volcanoes to erupt?
Ash and Gas make composite volcanoes erupt i believe

What kind of a hazard is volcanoes?
will make the people threaten, fuddled, heated kind of hazard
What are facts about strato volcanoes?
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?)
Do volcanoes make noise when they erupt?
Yes, volcanoes can make noise when they erupt. This noise can range from loud explosions to rumbling sounds, caused by the release of gases, magma, and other volcanic materials. The intensity of the noise can depend on the type of eruption and the volume of material being expelled.
Define active dormant and extinct volcanos?
active volcanoes release gases ash and lava. they make tremes or earthquakes and have a history of eruptions. the ground temperature increases and bulges appear on surface. dormant volcanoes don't have much happening. now and then it releases earthquakes. it has a history of eruptions and it could erupt again. extinct volcanoes cannot erupt again. it is done and finished. it no longer has gases and/or magma
Are there any good things from a volcanic eruptions?
they make new land and the volcanic ash from the volcanoes is goof for plant life and the plants grow much quicker.
What are the 3 types of volcanoes?
The three main types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are primarily built from lava flows. Stratovolcanoes are tall, steep-sided volcanoes composed of alternating layers of lava flows, volcanic ash, and other volcanic debris. Cinder cone volcanoes are small, steep-sided volcanoes formed from explosive eruptions that eject fragmented lava called cinders.
