We always talk about , what it would be like to see volcano eruption in front of your eyes ?
How amazing it would be like to find out , how the volcano erupt ?
There are many things that we don’t know exist in our earth 🌍. Do you want to know about it . If yes , than read the editorial .
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from Vulcan, the god of fire in Roman mythology.
Many ancient accounts ascribe volcanic eruptions to supernatural causes, such as the actions of gods or demigods. To the ancient Greeks, volcanoes’ capricious power could only be explained as acts of the gods, while 16th/17th-century German astronomer Johannes Kepler believed they were ducts for the Earth’s tears. One early idea counter to this was proposed by Jesuit Athanasius Kircher (1602–1680), who witnessed eruptions of Mount Etna and Stromboli, then visited the crater of Vesuvius and published his view of an Earth with a central fire connected to numerous others caused by the burning of sulfur, bitumen and coal.
Types of eruptions
- Hydrothermal eruption. An eruption driven by the heat in a hydrothermal systems.
- Phreatic eruption. An eruption driven by the heat from magma interacting with water.
- Phreatomagmatic eruption.
- Strombolian and Hawaiian eruptions.
- Vulcanian eruptions.
- Subplinian and Plinian eruptions.
How do volcanoes erupt?
Deep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth’s surface. Magma that has erupted is called lava.
The explosivity of an eruption depends on the composition of the magma. If magma is thin and runny, gases can escape easily from it.
Explosive volcanic eruptions can be dangerous and deadly.
Humans and volcanoes
Volcanic eruptions pose a significant threat to human civilization. However, volcanic activity has also provided humans with important resources.
Although volcanic eruptions pose considerable hazards to humans, past volcanic activity has created important economic resources.
Volcanic ash and weathered basalt produce some of the most fertile soil in the world, rich in nutrients such as iron, magnesium, potassium, calcium, and phosphorus.
Volcanic activity is responsible for emplacing valuable mineral resources, such as metal ores.
The paradox of volcanoes was that they were symbols of destruction but also life. Once the lava slows and cools, it solidifies and then breaks down over time to become soil – rich, fertile soil.Matt Haig, The Midnight Library
She wasn’t a black hole, she decided. She was a volcano. And like a volcano she couldn’t run away from herself. She’d have to stay there and tend to that wasteland.
She could plant a forest inside herself.
