If this happens, the flowing magma (now called lava) forms a volcano. The structure of the volcano, and the intensity of the volcanic eruption, is dependent on a number of factors, primarily the composition of the magma. In the next section, we'll look at some different magma types and...

How does an explosive eruption produce pyroclastic flow? How does magma form over an active subduction zone? What happens during a volcanic eruption? What happens after a volcanic eruption? How is basaltic magma transformed into felsic magma?
Products of an Explosive Stratovolcano Eruption The pyroclastic material flung into the air, known as tephra, ranges in size from tiny dustlike particles – ash – to house-sized volcanic bombs. Eruption clouds may rise 25 or more miles into the atmosphere, and they can drop ash (as ashfall...
aDuring an explosive eruption,pieces of rock are thrown from the volcano.Scientists call these pyroclasts.The smallest pyroclasts are called ash.Ash is often thrown into the atmosphere by the force of the eruption.Larger rocks,about walunt size,are called lapilli.Italian for"little stones."The...
from the bottle. build the pressure up in the bottle by shaking it and release the pressure and all that $500 bottle of champagne comes gushing out the top. that is, in a basic sense, what happens for an explosive eruption of a volcano -- volcanic gases come out of solution as the ...

yet end members are observed in nature for both cases. Lava lakes or Strombolian-style volcanoes are typical examples of open systems. Many very explosive eruptions show a phase of closed-system degassing with low levels of degassing prior to eruption169. It is very common for volcanoes to tran...
