Is a pyroclastic material high or low-viscosity?
Pyroclastic material can form with magma of any composition, but it is more likely to form with high-viscosity magma.
What is the viscosity of magma in a pyroclastic flow?
In a pyroclastic flow, the magma would almost always be considered high-velocity. The velocity and strength of the magma is a result of its chemical composition.
Why does pyroclastic flow travel faster than a lava flow?
Lava is a very viscous liquid, meaning it will resist flowing rather like syrup. Lava flows are often slowed even more as they form a crust of solid rock. A pyroclastic flow is a different matter; it is a dense cloud of hot ash, rock, and gas, behaving more like an avalanche than a flowing liquid. Pyroclastic flows are not slowed by viscous forces.
Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
Why might part of an eruption column collapse to form a pyroclastic flow?
Simple cooling of the ash and debris column, followed by collapse under gravity.
Is pyroclastic material likely to form from low- viscosity or high - viscosity?
Pyroclastic material is more likely to form with high viscosity magma.
Is a pyroclastic material high or low-viscosity?
Pyroclastic material can form with magma of any composition, but it is more likely to form with high-viscosity magma.
How pyroclastic flow form?
Pyroclastic flows form whenever the ash in a volcano builds up and is moved by the wind in large quantities toward a nearby city, town, or forest.
What is the viscosity of magma in a pyroclastic flow?
In a pyroclastic flow, the magma would almost always be considered high-velocity. The velocity and strength of the magma is a result of its chemical composition.
How does a pyroclastic flow form?
a pyroclastic flow is where u squeeze a massive spot (somewhat like a supervolcano) so hard it erupts and all the puss dribbles down ur facebook and drips off ur chin into the Atlantic ocean (ur bath tub)

Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
Are magma and rock both pyroclastic materials?
No. Magma is molten rock that is beneath earth's surface. When it erupts it can form lava or pyroclastic material. Although pyroclastic material can form rocks, most rocks are not from pyroclastic material.
Why might part of an eruption column collapse to form a pyroclastic flow?
Simple cooling of the ash and debris column, followed by collapse under gravity.
Is pyroclastic material likely to form from low-viscosity or high-viscosity lava?
low viscosity lava due to the violent eruption of the volcano
Can welded and cemented tuff result from same volcano?
Yes. A welded tuff may form from pyroclastic flow deposits near the volcano with cemented tuff farther away or resulting from a different eruption.
Is pyroclastic material likely to form from low-viscosity lava or high-viscosity lava?
