A grey volcano or in better terms a grey eruption is when the magma undergoes great pressure and stress and turns into the ashy substance, pressure builds and builds when finally the volcano erupts and releases the ash. then "energy waves" are spread out in all directions with such speed and force that they can strip trees and are nearly impossible to run from. The ash cloud is released to the atmosphere and if the quantity is great enough, " like the yellow stone caldera" it can encircle the world killing off plants from blocking out sun and when inhaled the moisture from your lungs transforms the ash to a cement like mixture and you drown in your own lungs. It only takes two inches of ash to collapse a building's roof. A red eruption is when the lava flows freely down in a slow movement and although highly destructive as well , you can run from a red eruption.

Can a volcano be gray?
Yes, ash volcanoes are generally grey because they're made of (yep, you guessed it) ash.
What land forms beside volcanoes are made by lava and ash?
the crust of the volcano
What is it called when ash and cinders are blown violently out of volcanoes?
when volcanic ash bursts out of the volcano, its called an eruption.^^^Actually, when ash and cinders are blown violently out of volcanoes, it's called a tephra. :3
Can the volcano have fire?
Volcanoes can start fires if lava or hot ash comes in contact with flammable material, but volcanoes do not directly produce fire.
Do volcanoes strike in the same place twice?
A volcano is a geologic feature, not an event. An event in which a volcano produces lava or ash is a volcanic eruptions. Virtually all volcanoes will erupt multiple times.
What are the 3 kinds of volcanoes?
shield volcanos, cinder cone volcanos , and composite
Layers of lava emitted by the volcano?
The different layers of a volcano are made from the lava and ash produced by the volcano. Some volcanoes have different thicknesses of layers or only one type of layer depending on the kind of eruption and how much ash it produces.
What are positive effects of a cinder cone volcano?
ash from volcanoes is good for trees because it makes furtilizer.
What are the positive effects of a cinder cone volcano?
ash from volcanoes is good for trees because it makes furtilizer.
Name three types of volcano forms?
shield volcano- volcano with whide crater developing from layers of lavacinder cone- small volcano with steep sides and explosive eruptions made of ash and rocks.composite volcano- tall volcano formed from eruptions of ash and rock followed by quiet lava flows.
What are the three types volcano?
A shield volcano, cinder cone volcano, and the composite volcano. Shield volcanoes are on of the three types of volcanoes. Shield volcanoes have quiet eruptions and the lava is basaltic. Its slope is shallow compared to a composite volcano and a cinder-cone volcano. They are produced by hotspots and mid-ocean ridge. Cinder-cone volcanoes are the second of the three types of volcanoes. Cinder-cone volcanoes. Cinder-cone volcanoes have explosive eruptions that release lava high in the air. They are created by tephra, volcanic ash. Its slope ranges between 30 degrees and 40 degrees. The lava is andesitic. Composite volcanoes are the third type of volcanoes. Their eruptions vary from loud and explosive to quiet. Composite volcanoes cab rise as high as 8000 feet and are steep. An example of composite volcanoes is Mount Fuji. Composite volcanoes spew felsic lava and they are built up by layers of harden lava, tephra, pumice, and volcanic ash.
When ash cinders and bombs build up in a steep pile around a volcanoes vent its called a?
composite volcano.
