Volcanoes vary a lot in how they erupt. The most important factor is the gas content of the magma. All magmas have gases dissolved in them, in the same way that soft drinks have carbon dioxide dissolved in to make them fizzy. As the magma gets close to the surface, the pressure on the magma decreases. That causes some of the gas to bubble out of the magma. Magma with low gas content comes out of the volcano without violent explosions and then flows peacefully down the sides of the volcano.
The more gases,water vapor and silica in magma the bigger the explosiveness of a volcanic eruption.
the more gas in magma makes it more explosive
Gas in the magma decreases viscosity and is what drives the explosive force of eruptions.
The amount of gas in magma determines the manner in which it erupts. A high gas content produces explosive eruptions while a low gas content produces effusive eruptions.
the gas thats going out of the volcano
There are two factors that determine how explosive a volcano is. The two factors are the amount of gas that is present in the lava and how easy or difficult that gas can be released into the atmosphere.
Typically, high viscosity, high gas magma results in a Plinian (explosive) eruption. The gas pulverizes the magma into ash and may form lateral pyroclastic flows.
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
Factors that determine the force of an eruption are magma viscosity and gas content.
it is a cloud that comes out of a volcano when there is a eruption
It is called Eruption.
Yes. More gas trapped in magma leads to a more explosive eruption. Water vapor is the most abundant gas in magma.

local people and the environment in which the volcano was in.
No each is different
How full the magma chamber is and the amount of gas that is in the volcano.

All volcanoes erupt for the same reason: magma making its way to the surface of the water inside the volcano, where it turns into steam and gas. The steam and gas propels the magma from the volcano, causing the eruption.
