What else can I help you with?
Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
How are pyroclastic materials classified?
Pyroclastic Material is classified by size from very fine dust and volcanic ash.
Is a pyroclastic material high or low-viscosity?
Pyroclastic material can have varying viscosities depending on its composition and temperature. However, in general, pyroclastic flows are typically low-viscosity due to their ability to flow rapidly downhill like a fluid.
Are cinders the most dangerous pyroclastic materials extruded from a volcano?
No. The most dangerous pyroclastic material is volcanic ash.
What type of pyroclastic material means little stones?
Lappili
What material is not a form of pyroclastic material?
Water is not a form of pyroclastic material. Pyroclastic material refers to fragmented volcanic rocks, ash, and other debris expelled during volcanic eruptions.
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.
Is a rock a pyroclastic material?
Some rocks are pyroclastic but most are not.
Is Pyroclastic rock basic or acid?
Pyroclastic material is more often felsic (acidic) or intermediate, but mafic (basic) pyroclastic material may also occur.
Is pyroclastic material poisonous gas?
No. Although a pyroclastic eruption will produce toxic gasses, the pyroclastic material itself consists of sperheated ash, pumice, and rock fragments.
Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
Is pyroclastic material likely to form from low- viscosity or high - viscosity?
Pyroclastic material is more likely to form with high viscosity magma.
How are lava and pyroclastic classified?
Both lava and pyroclastic material are classified as rocks. Lava is molten rock and pyroclastic material is various debris. There is Basaltic lava, Andesitic lava, Dacite lava, and Rhyolitic lava.
How are pyroclastic materials classified?

Are cinders the most dangerous pyroclastic materials extruded from a volcano?
No. The most dangerous pyroclastic material is volcanic ash.
What is a pyroclastic flow in volano?
Pyroclastic flow is gas that result from water mixing with loose material on the steep sides of a volcano.
