What is a volcano? A volcano is basically an opening or crack in the Earth's crust connected to a magma chamber and through which incandescent materials in the form of magma (lava, gas and liquids at high temperatures) from the interior of a planet emerge and accumulate on the surface of the planet. this.

Volcans

A volcano is a mountain or hill that has an opening through which gaseous, liquid or solid materials can escape from the interior of the earth. A volcano is a fissure in the Earth's crust on which a cone of molten, solid matter accumulates and is thrown through the chimney from the interior of the Earth. At the top of this cone is a concave formation called a crater. When activity occurs in a volcano it is said that the volcano is erupting. Volcanoes are generally structures composed of fragmented material and lava flows. Through the chimney, the molten rock that comes from the Earth's mantle comes out, which is known as magma. Once the magma comes to the surface, it loses the gases it contains because it evaporates, and when it runs down the slopes of the cone it is known as lava. This cone is formed by successive solidified layers, all inclined towards the outside of the chimney. The ejected rock material can reach between 4-200 kilometers (2-62 miles) in height. Typically, newly emitted lava ranges in temperature between 700-1,300 °C (1,300º-2,200ºF), depending on its chemical composition. Rocks that form from the cooling of magma are called igneous rocks. If the cooling took place deep inside the earth, and the molten rocks did not emerge to the surface, they are called intrusive igneous rocks. When rock has formed from the cooling of lava at the surface, it is called extrusive igneous rock. There are also igneous rocks which cool at great depth and these are known as plutonic rocks. Structure The parts of a volcano are: magma chamber, chimney, crater and volcanic cone.

The person who studies volcanoes is the volcanologist. But what is volcanology? Well, it is the study of volcanoes and is a subdiscipline of geology. The latter is the science that is responsible for studying the evolution of the planet through its internal composition, such as: Its minerals.

Volcan explication

The disqualification of Tamu from the list of largest volcanoes now leaves Mauna Loa as first classified, a 4,170-meter-high shield volcano located in Hawaii, of which there are records of up to 33 eruptions since 1843, three of which have occurred. covered with lava an area of ​​about 806...

When was the volcano discovered? Volcanoes: what they are and how they are formed As the oldest possible representation of a volcano seems to indicate, found in the Chauvet-Pont d'Arc cave, in the south of France and dated to 36,000 years old, . Volcanoes were also defined by the Greeks and Romans.
