Pumice and scoria have similar properties, like both being extrusive igneous rock with adjacent vesicles. Although pumice is less dense than scoria and its density is so low that it will float on water.
Ash and pumice are common materials.
Tephra.. (not pumice - Pumice is the light stone which forms during an eruption)
The main eruption of 1980 released ash, pumice, and gas. Smaller eruptions that occurred later produced very viscous lava that piled up into a lava dome.
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
Magma that reaches the surface erupts from volcanoes, either effusively to form lava or explosively to form ash, pumice and cinders. Lava and in some cases ash will then cool to form solid rock.
Lava is a hot liquid from the inside of the earth and ash is a lava powder, which is very hot.
Lava, ash, pumice and molten debris.
Tuff is a rock formed from volcanic ash and other debris, compacted and cemented together. It is typically fine-grained. Pumice is a type of volcanic rock that forms when frothy lava cools quickly, trapping gas bubbles in the rock. It is lightweight and highly porous.
Ash, Pumice, Pyroclastic flows, lanslides and obviously lava
Volcanoes can erupt ash, gas, and pumice in addition to or instead of lava.
Basalt, Andesite, Rhyolite, Obsidian, Pumice, Tuff, Ash (Lava).
No. Composite volcanoes erupt mostly ash and pumice.

No, pumice is a naturally occurring volcanic rock that forms when lava with high water and gas content is ejected from a volcano. Fly ash, on the other hand, is a byproduct of coal combustion in power plants.
Mount Pinatubo erupt violently, but does not produce lava flows. It creates massive clouds of ash and pumice.
