a lot
The pressure and heat in the volcano. When to much pressure builds it makes a eruption.
It is because the volcano has too much pressure
Volcanoes erupt when there is an earthquake or when there is too much pressure inside it.
because the pressure is caused by the plates grinding together if that stops no pressure
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.
a lot
A volcano can explode when pressure builds up inside it due to trapped gases and magma. This pressure can be released explosively when the volcano erupts, causing an explosion.
The amount of pressure that pushes up the magma in a volcano
A volcano can erupt when the pressure from below becomes too great.
Pressure and magma build up beneath the surface of a dormant volcano. This buildup can result in an eruption if there is a sudden release of pressure or new magma intrusion into the volcano's system.
Rocks fly out of volcanoes during eruptions due to the build-up of pressure from the molten rock, gas, and steam inside the volcano. When the pressure becomes too high, the volcano erupts, causing rocks and other materials to be forcefully expelled through the vent.
Lava erupts out of a volcano because of the pressure building up in the magma below.
