What are 4 different types of solid pyroclastics?
The 4 different types of solid pyroclastics are volcanic bombs, lapilli, volcanic ash, and volcanic blocks
Does mt Pinatubo erupt pyroclastics?
Yes. The 1991 eruption of Mount Pinatubo produced massive pyroclastic flows.
What causes lava to erupt as pyroclastics?
its when the lave and the valcano are 69ing and the valcano Cums
What rocks have rock fragments?
It depends on what you mean by rock fragments. But, if you are referring to rocks that have bits of blown up pieces of rocks in them, aka pyroclastics, then those are volcanic breccia and tuffs. These are made up of rocks such as rhyolites, andesites, or basalts.
What causes volcanism?
Volcanism is primarily caused by the movement of tectonic plates, allowing magma to rise to the surface and erupt. This can happen at subduction zones, mid-ocean ridges, and hotspot locations. Other factors like pressure and temperature within the Earth's mantle can also influence volcanic activity.
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 are three internal features of a typical volcano?
Internal features of a volcano include the crator, solidified lava flows (igneous rock), a volcanic conduit, pyroclastics, a magma chamber, areas of contact metamorphism, and sedimentary bedrock
Are pyroclastic rocks considered sedimentary?
Sometimes Pyroclastics are rocks formed from the cooling and solidification of material ejected during explosive volcanic eruptions, and are so primarily igneous. However, this material is often transported an redeposited by processes not directly related to volcanism. When this occurs, the resulting material may be considered sedimentary. Rocks that form from this transported volcanic material are called volcaniclastic rocks.
What are the similarities and differences between the types of volcanoes?
Shield volcanoes have fluid basaltic flows that are lower in silicates, making the lava very fluid without a tendency to form pyroclastics. Composite Cone volcanoes contain the highest percentage of silica content making the magma thicker with the greatest tendency to form pyroclastics and are the most dangerous volcanoes.
What three mountains form Mt. Fuji?
http://content.answers.com/main/content/wp/en/thumb/c/c3/120px-Fujiview.jpg "Fuji Volcano is a large composite stratocone consisting of alternating lava flows and pyroclastics. It is composed of three cones, Komitake, Older Fuji and Younger Fuji volcanoes, in order of decreasing age."

How are igneous metamorphic and sedimentary alike?
Igneous, sedimentary, and metamorphic rocks are differentin their method of formation. Igneous rocks solidify from melt, sedimentary rocks form from the lithification of sediments, and metamorphic rocks form from the application of heat and/or pressure over time. These rocks are alike in some ways, too, however. Igneous, sedimentary, and metamorphic rocks can share compositions -- they can be composed of cominations of biotite, calcite, quartz or other minerals. Their origin can also be shared. For example, a composite volcano has all three types: a sedimentary rock formed from welded pyroclastics, called welded volcanic tuff, piles up on the slopes. Lava solidifies on the slopes as well, forming igneous rocks. Inside the volcano, solid rock is exposed to heat but doesn't melt. This rock is transformed into metamorphic rock.
