What types of debris comes out of volcanoes?
Volcanic materials are divided into two main groups: Pyroclastic materials and lava flow materials.
Which type of the volcano gives pyroclastic debris?
Pyroclastic debris is usually produced by stratovolcanoes. However, shield volcanoes occasionally produce pryoclastic material in phreatomagmatic eruptions, which involve water interacting with magma.
What materials comes out of a volcano when it erupts?
A'a Lava (Pronounced as ah ah) Pahoehoe Lava (Pronounced as Pahoy-hoy) Pillow Lava Pyroclastic Materials
Are pahoehoe and AA produced during explosive eruptions?
No, pahoehoe and aa lava are typically produced during non-explosive eruptions. Pahoehoe lava has a smooth, ropey texture, while aa lava is rough and jagged. Explosive eruptions typically produce ash, pyroclastic flows, and lava domes.
What type of lava is least likely to form a pyroclastic flow?
Pahoehoe lava, which has a low viscosity and flows more easily, is less likely to form a pyroclastic flow compared to a'a lava, which is more viscous and tends to fragment into pyroclastic material when flowing.

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.
What type fo volcano is rabaul caldera?
a Pyroclastic Shield Volcano. Basically a shield volcano covered in pyroclastic debris from earlier eruptions.

What is another name for tephra?
Ashes, dust, cinders, scoria...

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.
What type of lava is least likely to form a pyroclastic flow?
Pahoehoe lava, which has a low viscosity and flows more easily, is less likely to form a pyroclastic flow compared to a'a lava, which is more viscous and tends to fragment into pyroclastic material when flowing.
Sometimes volcanic ash and debris rush down the side of a volcano is called what?
Pyroclastic flow
What are 3 examples of Pyroclastic debris?
Ash, pumice, and volcanic bombs are examples of pyroclastic debris produced during volcanic eruptions. These materials are fragments of volcanic rock that are ejected during explosive eruptions and can vary in size and composition.
Was the Soufriere Hills an AA or a pahoehoe eruption?
Neither. Pahoehoe and a'a are both basaltic lavas (mafic composition). Soufreier Hills erupts andesitic material (intermediate composition). This material took the form of ash and pumice forming pyroclastic flows (which are more like avalanches) rather than lava flows.
