The inner layers are laid down by earlier eruptions, and are then buried under ash and lava from later eruptions.

What is one type of plate boundary where volcanoes might form?

There are divergent boundries which causes Shield Volcanoes(an ocean volcano) and there a subducting boundries which causes a composite volcano(land volcano) there is also a cinder cone but that is made from a magma chamber(a place where magma is stored beneath the volcano and in the earths crust) explodes from being overfilled and layers upon layers form.


Could a composite volcano form in a desert?

Yes. Climate does not affect what kind of volcano can develop.


How do composite volcanoes form?

Composite volcanoes form from alternating layers of lava flows, ash, and volcanic rocks that build up over time. This type of volcano is created by a combination of explosive eruptions and lava flows, which allow for the formation of the steep symmetrical shape commonly associated with composite volcanoes.


What is the layers of rock around a volcano called?

The layers of rock form a dome called a laccolith


A mountain that forms when layers of lava and ash erupt and build up is a what?

what is mountain formed from layers of lava and ash


Is Mount Pinatubo a shield volcano a composite volcano or a cinder cone volcano?

Mount Pinatubo is a composite volcano, also known as a stratovolcano. It is characterized by its steep symmetrical cone shape and explosive eruptions caused by the combination of lava flows and pyroclastic material.


Can a composite volcano form in a pond?

Not really. While there is nothing that would prevent a composite volcano from developing under an area where a pond happens to be, there is no pond big enough to contain a composite volcano. As soon as the volcano starts forming, the first significant eruption would probably fill in or blast away the pond.


Is you true Shield volcano form from many thin layers of lava?

No


What is layer of lava and ash?

When molten rock (lava) flows from a volcano, it covers the surrounding area in a layer of solidified rock. During the eruption, ash can also be thrown up high into the sky by the volcano, and blown by the wind, could settle in a thick, smothering layer. The city of Pompeii suffered from being smothered by volcanic ash.


A composite volcano is most likely to form where?

A composite volcano is most likely to form at subduction zones where an oceanic plate is being subducted beneath a continental plate. The interaction between the two plates causes magma to rise, leading to the formation of a composite volcano due to the explosive eruptions caused by the high silica content in the magma.


What kind of eruption form composite cone volcano?

Composite volcanoes are highly variable in what they erupt. Most often, eruptions will release clouds of ash, pumice, and rock fragments. In some cases they fountain or extrude lava.


How do a composite volcano form?

composite volcanoes form when you toss a cooked muffin into the mouth of a hurricane on the 18th of may next year. But only if you're chuck Norris
