Volcanoes have always attracted universal interest and frightened the population. It is not worth recalling how the volcano destroyed the ancient Roman city of Pompeii. Even in the modern world, people cannot prevent eruptions, but are forced to flee. Scientists from around the world study and learn new information about these mysterious objects that attract the attention of not only scientists, but also ordinary people. In this article, we learn the name of the vents of the volcano and other interesting facts about these deadly giants.
Terminology
The volcano is a block of rock rising above the surface of the earth, in which there is a hole of continuous depth connecting magma with the surface. This hole is popularly called the vent or vent of a volcano, but it also has a more scientific name - nekk. This word comes from the English neck, which literally translates as neck. Indeed, the mouth of a volcano can be compared with its neck, because, as a rule, it has a cylindrical or almost cylindrical shape.
Kinds
If we consider the neck of the volcano in cross section, then it can be of several types: round, oval or indefinite. The size of the nekk varies from three / four meters to one and a half kilometers. Some of them even exceed this diameter. After the destruction of the material forming the volcano (since this material is quite loose and not strong), the necks still remain, rising above the ground, like huge pillars, since they are formed from harder rocks. It often happens that they contain ores and other minerals.
