A Volcano is defined to be a chimney or a vent where molten rock known as magma can escape from underneath to the Earth's surface. When the magma is erupted from a volcano, it is then called a lava. In terms of appearance, there is a wide variety of appearance with some featuring perfect cone shapes while others are deep depressions filled with water. The frequency, style and size of eruptions can differ but in all totality, these elements correlated to the shape of a volcano.

​

A Volcanic Eruption is described by volcabulary.com to be "the sudden occurrence of a violent discharge of steam and volcanic material". When a stream of gas, ash, and magma is violently ejected to a height of several miles.

Volcanic eruptions mainly occur as a means of how earth (and other planets) cool off and release pressure. It all begins when molten rocks found in the lithosphere and asthenosphere are melted into magma due to the core's high temperature. This in turn builds up and thickens rising up to form a magma chamber.

Over time, the gases in which magma is composed of expand and continually increase in volume. This further results to the increase in pressure and the injection of new magma on the chamber until it could no longer contain everything in and an eruption ensues.
