Magma in mantal is under great heat and high temperature. Once there is a crack or we called a line of weakness appears on crust's surface,magma would escae to the surface from mantal.Volcanic ashes,gases and magma would throw out and causes volcanic eruptions.
Since the magma is always building up pressure and the earth is always spinning, it sometimes causes a crack in the earth. The two sides of the crack may shift. This is called plate tectonics, known to be the cause of volcanic eruptions. The magma will burst through the crack. When magma comes out or erupts, it is called lava. If this crack is in the ocean, an island can be created. After it erupts numerous times, a cone is created. When there is an eruption in a volcano, the place where pressure builds up and where the magma is is called the magma chamber.
The amount of pressure that pushes up the magma in a volcano
The factors are: Viscosity, Dissolved Gasses, Volcanic Materials, and Pyroclastic Materials. :) :P
magma and heat preasurizing

No. There is nothing any person can do to cause or prevent a volcanic eruption.
It's eruption.
Plate tectonics
A volcanic eruption underwater is called a submarine volcanic eruption. By contrast, a volcanic eruption on land is called a subaerial eruption.
Yes. Krakatoa was a volcano. Therefore the eruption of Kraktoa was a volcanic eruption.

Cows and volcanic eruption.
When tectonic plates go under each other.
A destructive margin
Yes. Krakatoa was a volcano. Therefore the eruption of Kraktoa was a volcanic eruption.
The deadliest volcanic eruption in the world was the eruption of the Tambora volcano in 1812, It caused an estimated 92,000 deaths.
No, climate and weather do not cause volcanic eruptions. However weather affects the products produced by a volcanic eruption.
