What Pyroclastic material less than 0.25mm in the diameter called?
Pyroclasts are single fragments that are produced following a volcanic eruptions where there expanding gases rapidly erupt resulting in either the fragmentation or obliteration of rock and magma. Fine-grained pyroclastic material is generally made from ash cause by extremely high fragmentation of rock or magma.
What is true about volcanic glass?
Volcanic glass is the amorphous (uncrystallized) product of rapidly cooling magma.
Is scoria volcanic glass?
Yes.Scoria ("lava rock") is found on the surface of lava flows or in fragments that have ejected from the volcano's explosive opening. In these conditions, the molten rock was immediately exposed to the open air on the Earth's surface, causing it to cool and solidify very rapidly. This solidification process is too quick for atoms within the solution to bind together to form large crystals, so the solid rock is consequently made up of tiny glassy fragments that are amorphous, or do not contain crystalline structures. Since scoria is made up of these glass fragments, it is defined as VOLCANIC GLASS.
A rapidly moving mixture of volcanic debris and water is a?

What is a vent or opening through which volcanic gases and smoke are realeased?
This is known as a volcanic vent.Gas and lava exit a volcano are through a volcanic vent or fissure and cool rapidly at the surface. Eruptions can be fluid or explosive.

What makes up pyroclastic flow?
Pyroclastic flows are fluidized masses of rock fragments and gases that move rapidly in response to gravity.
Why does your car overheat at high revs?
Because the coolant is flowing too rapidly for transference of heat. That is why it is not a good idea to run without a thermostat. Water can circulate too rapidly to do any cooling.
What is the type of mass movement by which a mixture of water rock and soil moves rapidly downhill?
air and soil if you havy any comment find me at hkedash@yahoo.com
How magmas evolve?
Where magma erupts on the surface of the earth, temperatures are lower and cooling of the magma takes place much more rapidly. This is the extrusive or volcanic environment and results in extrusive or volcanic igneous rocks.
What type of rock had no visible crystals as result of rapid cooling?
Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.
