What is the cause of the volcano?
The volcanoes are the visible manifestations of the internal activity of the Earth. They are formed when magma of more or less deep origin reaches the surface of the globe through cracks.
How to volcanoes are formed? One volcano arises following the arrival on the surface of the earth’s crust of a large mass of molten rock, magma. Arriving at the surface, the gases of the magma can escape, explode and cause the spectacular explosive manifestations of volcanism.
One volcano is composed of three parts: the reservoir of magma which is in depth, one or more chimneys which allow the magma to escape from the reservoir in the direction of the surface of the tectonic plates, and on the surface, the device volcanic whose composition varies according to the type of volcano (flows of …
The main bodily injuries are fatal burns caused by volcanic flows, asphyxiation by inhalation of ashes and gases at very high temperatures, or the collapse of the roofs of houses overloaded with tephra (ash, pumice).
How did she wake him up? It’s quite simple, it involves heating this paste slowly, very slowly since it is very viscous, and this process took several tens, hundreds, even several thousand years. So an extremely slow process. This is called conductive heating.
He accumulates in the magma chamber, who is a huge reservoir of magma located between 10 and 30 km deep in the lithosphere. Gases mix with the magma, creating an increase in pressure.
Volcanoes are formed with the rise and accumulation of ash, dust and magma (a mixture of molten rocks and gases from inside the earth) above the surface of the globe called “the earth’s crust “. The magma expelled from the volcano is called lava.
A volcano is an opening or break in the earth’s crust through which magma or lava is discharged from the earth’s interior in the form of lava, volcanic ash and high temperature gases. They usually form at the edge of tectonic plates. The formation of volcanoes has different processes:
Volcanism was born at the same time as the Earth, during the accretion phase of its formation 4.6 billion years ago. From a certain mass, the materials at the center of the Earth undergo significant pressures, thus creating heat.
Etymology. The masculine noun “volcano” is a borrowing from the Spanish volcán, a masculine noun of the same meaning, derived, through the Arabic burkān, from the Latin Vulcanus, name of Vulcan, the Roman god of fire, and from Vulcano , one of the Aeolian Islands, a volcanic archipelago off the coast of Sicily.
