Lava is simply molten rock on the surface of the earth that flows as a viscous liquid. Pyroclastic material consists of rock fragments, molten, and partially molten material that is blasted out by explosive volcanic activity and eatiher rains down or flows downward as a density current.

∙ 11y agoA pyroclastic flow is a fast-moving avalanche-like phenomenon made of hot ash, rock, and gas that results from an explosive volcanic eruption.
Pyroclastic material is stuff that is carried and deposited by pyroclastic flows and similar phenomena.

How are lava and pyroclastic material 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.
What kind of material comes out of Mt Etna lava or pyroclastic material?
Both come out of Mount Etna. It is a composite volcano which means it alternates between erupting with pyroclastic material and lava.
What is the difference between pyroclastic flows and lava flows?
Lava is molten rock at earth's surface. A pyroclastic flow is an avalanch-like flow of hot ash, rock, and gas that moves down a volcano's flanks at great speed.
Is pahoehoe considered pyroclastic debris?
No. Pahoehoe is considered a lava flow. Pyroclastic debris consists of volcanic ash, pumice, and lapilli rather than lava flow material.
What are the materials emitted or produced during volcanic eruption?
The materials associated with volcanic eruption are Lava flows such pahoehoe lava and Aa lava. Gases that contain mainly water vapor and carbon dioxide. Pyroclastic materials such fire fragments, ash, dust, pumice, lapilli, cinders, harder lava and hot lava as bombs.

Both come out of Mount Etna. It is a composite volcano which means it alternates between erupting with pyroclastic material and lava.
Is a non-explosive volcanic eruption more likely to produce lava or pyroclastic material?
Lava because pyroclastic material explodes from a volcano, Lava just runs down the surface of the volcano nonexplosive or explosive.
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 difference between tephra and pyroclastic flow?
Tephra flow is fragments of volcanic rock and lava. Pyroclastic flow is fast moving current of hot gas and rock.

What type of pyroclastic material comes out of a shield volcano?
ash cloud lava
Is pahoehoe considered pyroclastic debris?
No. Pahoehoe is considered a lava flow. Pyroclastic debris consists of volcanic ash, pumice, and lapilli rather than lava flow material.
Are basalt rocks pyroclastic?
Usually not. Although it is possible to have pyroclastic material with a basaltic composition, most basaltic rocks are from simple lava flows.
What are the materials emitted or produced during volcanic eruption?
The materials associated with volcanic eruption are Lava flows such pahoehoe lava and Aa lava. Gases that contain mainly water vapor and carbon dioxide. Pyroclastic materials such fire fragments, ash, dust, pumice, lapilli, cinders, harder lava and hot lava as bombs.
What igneous rock is formed from magma or lava cools and hardens?
Cooled magma, lava, or pyroclastic material is igneous rock. Cooled magma forms intrusive igneous rock, while lava and pyroclastic material form extrusive rock. Anything beyond that depends on more specific factors.
