How often does a volcano eruption occurs?
Pressure. Pressure causes the molten to rise if the volcano is capped off, the presure builds till it eventually explodes, spewing lava and dust clouds, and showering rocks everywhere.
The glottis closes off the larynx so pressure in the lungs builds before what explosive phenomena?
Sneeze
What is the couse of a eruption in a volcano?
Well first off...techtonic plates create the mountain called the volcano. One techtonic plate goes under the other and forces the other techtonic plate to go upwards creating a mountain, but the inside of the mountain is then filled with the earth's core or lava. Then pressure builds up inside the mountain until it can't take that much pressure and erupts. This is one of many ways a volcano eruptps, but it is the most common.
Is Krakatoa a explosive or non-explosive?
Krakatoa is a volcano that erupted. In the eruption, gases were trapped below the cap of the volcano. The explosive eruption occurred when the pressure was enough to blow the cap off of the volcano.
Why wont your 90 Chevy truck start until oil pressure builds up?
there is a second oil pressure switch that shuts off the fuel pump if theres not enough oil pressure
Can volcanoes always be danger?
Yes, because you never know when the pressure can build up and blow the top off the volcano but if a volcano is dormant or extinct it is very unlikely.
What can cause a death to a volcano?
There are several once active volcanoes round the world that have become dormant long ago. The magma flowing beneath, may have found another weak spot , so taking the pressure off the once active volcano. Without the pressure, the volcano can cool down and become dormant. There is always the chance that a dormant volcano can become active again - it depends mainly on the pressure below - and often causing even more devastation as the cap is blown off.
What mountain is formed by geothermal pressure or material discharge?
The materials that have been ejected off a pressured mountain is called a "VOLCANO"
Why does my van leak coolant when I shut it off but not while running?
Pressure builds when you shut it down but should still not exceed pressure on cap, look into what is causing loss of cooling system efficiency
What is an extinict volcano?
An extinct volcano is a volcano that is completely cut off of its magma supply.
What keeps the high pressure from the low pressure in a 1993 Chevy lumina car When I charge my system and the compressor stops the pressure in the suction line builds back up to 100 plus psi.?
When the system is off the pressure will equalize through the orifice tube and the compressor. It's normal operation.
Can a volcano be grey but not ash volcanoes?
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.
