A pyroclatic flow is a superheated flow of hot air, debris, ash. boulders and toxic gases. The Pyroclastis flow comes pouring down the volcanoe at 140-150 MPH
the temperature can be around 1000 degrees Celsius.
Best hope you're not around when one of these go off. Also never get by the lava after it has been erupted!!!!!!!
What else can I help you with?
What materials are ejected from volcanos?
Pyroclastic Materials. Any composition of lava can produce pyroclastic materials. Pyroclastic fragments are ejected from the volcano as solid fragments, often solidifying as they leave the volcanic vent, or fly through the air. Tephra comes in all sizes.
What is Pieces of rock and debris that are carried within lava and propelled through the air during an eruption are called?
Volcanic airborne debris is classified as either solid (tephra, aka pyroclasts, including "volcanic bombs") or particulate (ash). Lava chunks ejected into the air around a vent is called "spatter."*When solids condense from gaseous pyroclastic flows, the rock material is called ignimbrite.
What is medium-sized tephra?
Medium-sized tephra consists of pyroclastic material that falls between fine ash and coarse lapilli in size. It typically ranges from 2 to 64 millimeters in diameter and is produced during explosive volcanic eruptions. Medium-sized tephra can pose hazards to aviation, infrastructure, and human health depending on the volcanic activity.
What are 10 vocabulary words for the famous volcanic eruption of Kilauea?
Lava Ash Pyroclastic flow Volcanic plume Caldera Lahar Vent Tephra Fissure Geothermal activity
What is the name of the largest sized tephra?
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
What is another name for tephra?
Ashes, dust, cinders, scoria...
What volcanic material includes ash cinders and bombs?
Tephra, or pyroclastic materials deposited by falling through the air.
What is the difference between tephra and pyroclastic flow?
Tephra refers to fragmented volcanic material ejected during an eruption, including ash, lapilli, and bombs. Pyroclastic flow is a fast-moving mixture of hot gas and volcanic particles that flows down the side of a volcano during an explosive eruption, capable of reaching speeds of hundreds of kilometers per hour and causing widespread destruction.
Clouds of very hot tephra that contain poisonous gases and move quickly down the flanks of volcanoes are called?
pyroclastic flows :-)

What term describes fragmental volcanic material?
Fragmental volcanic material is often referred to as pyroclastic or tephra, which includes ash, lapilli, and larger volcanic blocks and bombs produced during explosive volcanic eruptions.

What is the name of the largest sized tephra?
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
What Pyroclastic material less than 0.25mm in the diameter called?
Pyroclasts are single fragments that are produced following a volcanic eruptions where there expanding gases rapidly erupt resulting in either the fragmentation or obliteration of rock and magma. Fine-grained pyroclastic material is generally made from ash cause by extremely high fragmentation of rock or magma.
The ancient city of pompeii was destroyed when a mixture of hot volcanic gases, ash, and rock poured down mount Vesuvius and covered the city. Which two terms describe the substance that was produced by the volcano?
A. Pyroclastic Flow and D. Tephra. Apex
