Volcanic eruptions range from explosive to quiet depending on the viscosity of the magma & the amount of dissolved gases. Felsite volcanoes are the most viscous & the most explosives. The explosive products from a volcano are called pyroclastic rocks. Thus the most explosive volcano are those whose composition is felsitic.This viscous felsite may plug the vocano, causing the pressure to build within it. When the pressure becomes great, an explosive eruption will occur. That is how composite volcoanos are formed.

Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
What kind of lava do Composite volcanoes produce?
it has mafic and felsic duhhhhh
Is mauna kea mafic or felsic?
As a shield volcano, Mauna Kea erupts mafic lava.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Do composite cone volcanoes have mafic 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.

Does a composite volcano have mafic lava?
While some textbooks might say "no", the real answer is "sometimes". Composite volcanoes are highly varied in what they erupt with magmas across the whole range from mafic to felsic. On average the rock in most composite volcanoes is intermediate.
Do composite cone volcanoes have mafic 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.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.
Does paricutin mafic or felsic lava?
Paricutin erupted mafic lava.
Is mafic or felsic lava produced in mt fuji?
mafic lava is the KIND of lava produced in mount (mt) Fuji.
Which cools faster mafic or felsic rocks?
mafic because it is-dark colored. Ultramafic - no light colored mineral which means it it attracts most heat from a volcano taking it longer to cool down from the lighter, in between substance known as felsic :D
Does mauna loa have mafic or felsic magma?
Mauna loa erupts mafic lava.
Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
