How Often Do Volcanoes Erupt

my paper I will be giving information on how often do volcanoes erupt. First,I will explain how magma can trigger volcanic eruption. Next, I will discuss how buoyancy can also trigger a volcanic eruption. Finally, I will predict how pressure from gases in the magma and magma chamber can cause a volcanic eruption,and give some more details about my volcano.
It depends on the volcano to erupt oftenly. Some volcanoes erupt very often (and some like Kilauea almost never stop). On the other hand, some volcanoes are inactive for very long periods of time between eruptions.There are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma chamber,Bodies of magma rise in the crust until they reach a point of neutral buoyancy. The expansion of gases brings the magma closer to the surface and …show more content…
A volcano is an opening in the earth’s surface from which gas,hot magma and ash can escape.The word volcano comes from the Roman name Vulcan the Roman god of fire. Volcanoes are often found meeting points of what are called tectonic plates.350 million,or one in 20 people in the world live within danger range of an active volcano.Volcanoes aren’t only found on the boundaries of tectonic plates though,they can also occur over mantle plumes super hot areas of rock inside the
