A pyroclastic bomb is a big rock that can be spewed, blasted, or carved out of a volcano. They are usually deermined by their size and how dense the rock is
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
Pyroclastic flow
No. A pyroclastic flow can move at well over 100 mph.
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.
Pyroclastic flows can be of any composition, but are more commonly felsic or intermediate.
Pyroclasts. I.e. Pyroclastic materials such as Lava bombs.
Some rocks are pyroclastic but most are not.
Pyroclastic flow.
volcanic pyroclastic = 'a'ā
an explosive volcano will usually have a pyroclastic flow
Yes. It is not uncommon for rhyolitic material to form pyroclastic flows.
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.
Pyroclastic flow
Pyroclastic material is more often felsic (acidic) or intermediate, but mafic (basic) pyroclastic material may also occur.
No. A pyroclastic flow can move at well over 100 mph.
No. Although a pyroclastic eruption will produce toxic gasses, the pyroclastic material itself consists of sperheated ash, pumice, and rock fragments.
Water is not a form of pyroclastic material. Pyroclastic material refers to fragmented volcanic rocks, ash, and other debris expelled during volcanic eruptions.
