Volcanic Eruption May Have Triggered Black Death Pandemic New Study 'butterfly Effect' That Led To The
Volcanic eruptions are among the most stunning phenomena in the natural world. The term volcano can also refer. Owing to the aphanitic texture of volcanic and hypabyssal rocks, their modes cannot be readily determined;
Volcanic eruption may have triggered Europe's deadly Black Death plague
A volcanic eruption is an eruption of molten rock, hot rock fragments, and hot gases through a volcano, which is a vent in a planet’s or satellite’s crust. (1) plutonic intrusive igneous rocks that solidified deep within the crust and (2) volcanic, or extrusive, igneous rocks formed at earth’s surface. A relatively small number of volcanoes occur within plates far from their margins.

Volcanoes erupt because of the way heat moves beneath earth ’s surface. Volcano, vent in the crust of earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases. Volcanic activity is also common at divergent boundaries, where two plates slowly pull apart and allow molten rock to escape to the surface; This results in two groups:
Each of the more than 1,500 potentially active volcanoes or volcanic areas around the world has a distinct form, though most can be generalized into nine categories (see table). This magma rises to the surface and gives birth to a line of volcanoes in the overriding plate, known as a volcanic arc, typically a few hundred kilometres behind the. Volcanoes are frequently classified by their size and shape (as is described in the section volcanic landforms), but they can also be classified. Some, as exemplified by the volcanic islands of hawaii that lie in the interior of the pacific.
