How does the magma rise from the volcano?
magma rises up out of a volcano by the build up of pressure
How does a volcano interrupt?
A volcano erupts when gases build to an inescapable high pressure. The gas pushes magma and ash through the cone of the volcano causing an eruption.
What is happening to the plates that formed the Colima volcano in Mexico?
The plates are colliding and causing pressure to build there for it is building up the volcano by pushing it up
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.
Why is a convergent volcano not a volcano?
because the pressure is caused by the plates grinding together if that stops no pressure
What makes a Volcano work?
The pressure and heat in the volcano. When to much pressure builds it makes a eruption.
What are the steps a volcano has to go through to erupt?
1. Pressure in the magma chamber begins to build up. 2. The pressure forces the magma to go up through the vent. 3. Then it will erupt
How does a volcano build into a mountain?
A volcano forms a mountain as ash and/or lava build up over time from successive eruptions.
What is the pressure of a volcano?
a lot
What triggers the small earthquakes the occur around a volcano before an eruption?
Increases in seismic activity around a volcano are typically caused by the movement of magma below the surface into a magma chamber. This causes increases in pressure which leads to fracturing to the rock mass around the magma chamber causing small earthquakes. If the pressure continues to build it would ultimately force the volcano to erupt.
What type of plate boundary is creating mt hood?
It is on a convergent plate boundry forming a subduction zone which build pressure in the volcano causing them to erupt.
How much pressure is in a volcano?
a lot
