Want this question answered?
Magma(or lava if it is already above or out of the volcano
yes, I think so. because, very large volume of magma is ejected and then magma chamber can't support the volcano above it. then the volcano begins to sink into the earth.magma chamber empties and a new collapsed depression occurs.
Lava is the name given to magma which has been erupted onto the earth's surface. Magma in turn forms by the partial melting of material in the upper mantle, usually caused by either the release of "volatiles" - water / gases etc into the mantle from a subducting slab of oceanic crust which acts to lower the temperature at which it will melt or by decompression melting of up welling mantle material.
The ring of fire is a group of volcano's surrounding the pacific. Volcano's are formed by 2 continental plates colliding and a magma chamber was under neath. It is named ring of fire because it is a ring of volcano's.
If you get a very sticky magma (molten rock) which can occur due to the composition of the magma it makes it hard for gas to escape (e.g. think of blowing bubbles through honey and water, its harder through honey), when the gas does escape out of these sticky magma's it has built up a lot of pressure and explodes.
Cause it was one of the first volcanos

Rocks, magma, what else? WHAT ELSE YOU ARE DUMB read on. you can find diamonds, copper, gold , zinc and lead that is formed within the volcano why do you think that they have got mines in the USA into the volcano

uhm i think its shield volcano but im not sure ...... but i kno its between A, HOT SPOT B, CINDER - CONE VOLCANO C, COMPOSITE D, SHIELD VOLCANO or the storage of magma under the volcano
I think it is all to do with the pressure forming underneath the earth's crust in the mantle and magma chamber hope this helps!
In order for a volcano to erupt, magma must move toward the surface. This causes rock to shift and break underground, generating earthquakes.

Viscosity refers to the amount of internal friction in a substance which affects the ease with which it flows. Magma has a wide range of viscosity depending on the composition of the magma. The viscosity increases as the silica content changes from basalt to rhyolite. The more viscous a magma is, the slower it flows.
