Volcanic eruptions are caused when magma from the magma chamber of the Earth rises up the pipe and out of the vent. Magma is continuously supplied from the mantle of the Earth. Shield volcanoes usually have a gentle eruption, as it contains basic lava. Acid-lava and composite volcanoes usually have a violent eruption as it contains acidic lava. The vent of the volcano might also be blocked, causing the magma to force its way out, thus causing a huge explosion.
In a more specific way, volcanoes erupt when rock releases pressure. It spreads and creates magma and if the magma is felsic lava it will be thick and will create large eruptions but mafic lava is very watery and creates small runny explosions and it also depends what kind of volcano it is because its eruption varies upon its formation.
There are plates that are always shifting around in the ground. They move 1cm every day. When the plates collide,they make a big BOOM which cause the things in the volcano to heat up. Then the heat pushes everything to the opening in the volcano which causes it to erupt and shoot out.
Volcanic eruptions are caused by the movement of magma (molten rock) beneath the earth's surface. When pressure builds up and forces the magma to the surface, it erupts through a volcano's vent, leading to an eruption. Other factors such as tectonic plate movements, gas buildup, and the composition of the magma can also influence volcanic activity.

Are volcanic eruptions rare?
Volcanic eruptions are common in some of the Earth's volcanic hot-spots.
Is igneous released in volcanic eruptions?
Correct. Igneous rocks fly out of volcanic eruptions
What are the three main causes of volcanic eruption?
The three main causes of volcanic eruptions are the accumulation of magma beneath the Earth's crust, the buildup of pressure within the magma chamber, and the release of gases trapped in the magma. These factors can lead to explosive eruptions that result in the expulsion of ash, lava, and volcanic gases.

Is igneous released in volcanic eruptions?
Correct. Igneous rocks fly out of volcanic eruptions
What are the kinds of volcanic eruptions?
The kinds of eruptions are the quiet eruptions and the explosive eruptions.
What are the three main causes of volcanic eruption?
The three main causes of volcanic eruptions are the accumulation of magma beneath the Earth's crust, the buildup of pressure within the magma chamber, and the release of gases trapped in the magma. These factors can lead to explosive eruptions that result in the expulsion of ash, lava, and volcanic gases.
