Highly viscous magma produces explosive volcanoes, which can quickly move huge volumes of material which could be impossible to escape.

Highly fluid magma tends to produce slow moving, flowing lava, which does not create the destruction associated with explosive volcanoes.

Is a dome volcano the same as a cone volcano. if not - what is a dome volcano?

a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.


Is mount nyiragongo a shield volcano?

No, Mount Nyiragongo is a stratovolcano, also known as a composite volcano. It is characterized by its steep-sided cone shape and explosive eruptions due to the presence of viscous magma.


Difference between viscous and non viscous lava?

Viscous lava is very sticky and thick and is more felsic (ie it contains more silica) than non-viscous lava. This type of lava makes for a very explosive volcano, because it's so sticky that it sticks to itself and can't exit the volcano until it explodes violently. Non-viscous lava is more runny and is more mafic (has more iron, less silica). Volcanoes with non-viscous lava are less explosive because the lava just runs out slowly and no pressure builds. The Hawaiian islands are formed from volcanoes with non-viscous lava.


Is galeras volcano cinder composite or shield?
