Water !!. . . naah Magma what else ?? !!
pressure
A mountain formed by the build up of lava and ash is a composite volcanic cone.
Nobody knows because volcanoes just erupt when the lava builds up and is forced up the main vent and out of the crater!
A volcano can erupt many times. If the pressure from below builds up too much, the volcano will erupt, throwing out very hot gases and lava, until the pressure has been released.

Volcano.
Volcanos are scientists window to the mantle and core past the crust. Or volcanoes erupt when pressure builds up then explodes!
Yes, a volcano can erupt multiple times throughout its lifespan. Volcanic eruptions occur when pressure builds up within the magma chamber beneath the volcano, causing it to release lava, ash, and gases. Some volcanoes can remain active for years or even centuries, erupting multiple times during that period.
Silt
Magma builds up in the mountain and starts to rumble. Then the rock at the bottom starts to push up causing the magma to go up and rise the temperature of it. As it nears the opening it becomes lava and turns into ash as it burns up.
