because the pressure is caused by the plates grinding together if that stops no pressure
The pressure and heat in the volcano. When to much pressure builds it makes a eruption.
a lot
A volcano can erupt when the pressure from below becomes too great.
The amount of pressure that pushes up the magma in a volcano
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.
magma rises up out of a volcano by the build up of pressure
A volcano " vents " gas when pressure builds up
Pressure.
A volcano is a mount (or mountain) that has magma in it. A volcano also is like an earthquake releasing pressure from the inner core of the earth. If there is a lot of pressure to be released this will cause the eruption to be bigger and more destructive, like the volcano Mount Tambora that erupted in 1815.
A volcano is the visible effect of pressure building up in the semi-molten mantle below the surface. This pressure can cause lava and gases to erupt from the opening in the top or sides of the volcano. Therefore, a volcano occurs on the earth's crust (surface).
Gases and rocks shoot out of a volcano due to the build-up of pressure beneath the Earth's surface. This pressure is caused by the movement of magma and gas within the volcano. When the pressure becomes too high, the volcano erupts, expelling gases, rocks, and other volcanic material.
