A pyroclastic bomb is a volcanic rock fragment ejected during explosive eruptions. These bombs are molten or semi-molten when they are launched into the air and solidify as they cool down, forming aerodynamic shapes due to the velocity of their launch. They can vary in size from centimeters to meters in diameter and can cause damage or injuries if they land near populated areas.

Can rhyolite be pyroclastic?
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Can you outrun a pyroclastic flow?
No. A pyroclastic flow can move at well over 100 mph.
Does Krakatoa produce lava or pyroclastic flow?
Yes, of course Krakatoa has a pyroclastic flow. Every volcano has an pyroclastic flow, which can travel up to at huge speeds. Krakatoa's pyroclastic flow raced an amazing 200 mph over 20 miles of open sea. Yes Krakatoa has pyroclastic flows but not all volcanoes produce pyroclastic flows, only Mt. St. Helens type volcanoes usually composed of andesite. Kilauea for example does not produce pyroclastic flows because it is composed of basalt, the lava flows out easily.
How are pyroclastic materials classified?
Pyroclastic Material is classified by size from very fine dust and volcanic ash.
What is the largest rock fragment blown into the air during a volcanic eruption?
Pyroclasts. I.e. Pyroclastic materials such as Lava bombs.
What is the Hawaiian name for volcanic pyroclastic?
volcanic pyroclastic = 'a'ā
What is more deadly lava or pyroclastic flow?
Pyroclastic flow.
Is a rock a pyroclastic material?
Some rocks are pyroclastic but most are not.
What volcano produces a pyroclastic flow?
an explosive volcano will usually have a pyroclastic flow
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.
What is the term for lava flow that travels downhill at over 100mph?
Pyroclastic flow
Is Pyroclastic rock basic or acid?
Pyroclastic material is more often felsic (acidic) or intermediate, but mafic (basic) pyroclastic material may also occur.
Can you outrun a pyroclastic flow?
No. A pyroclastic flow can move at well over 100 mph.
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.
What kind of type of lava does a Pelean eruption have?
A pyroclastic eruption, involving a viscous magma, typically of rhyolitic or andesitic type. An ignimbrite is the deposit of a pyroclastic density current, or pyroclastic flow.
