Super Volcanoes

Super Volcanoes
There is no exact definition for a super volcano, but the expression is often used to refer to volcanoes that have produced extraordinarily large eruptions in the past. When one of these large eruptions occurs, a huge amount of material is blasted out of the super volcano, leaving a massive crater or caldera. A caldera can be as much as forty or fifty miles wide. At Yellowstone, the caldera is so big that it includes a fair amount of the entire park. In effect, it is so big that at first scientists didn?t see the state a caldera had until it was photographed from space. Super volcanoes are formed when magma rises from the mantle to create a scorching reservoir in the Earth?s crust and they start to form in layers. This chamber increases to a gigantic size, building up huge pressure until it finally erupts. After it finally erupts, the calderas collapses.
When the reservoir has formed, a substance is collected that will trap the volcanic gases. They form depressions in the ground and it is very hard to imagine the eruptions, explosions, car atrophic proportions that they cause. Super volcanoes produce vast amounts of ash and destruction. There are thousands of normal volcanoes around the world and at least 50 erupt every year. Vast clouds of ash are deafening sounds; it affects the climate on earth for many years and affects the agriculture colour. At yellow stone, if the substance is plunged into catastrophe, this means that humans could become distinct. Super volcanoes cause unimaginable forces and affect everything in ways that humans cannot begin to imagine. There are many pieces of evidence that prove that Super volcanoes do exist. The first is that all animals were infected, from the orchard, abruptly, ten million years ago. These included bones of fossilised rhino, horses, camels, and lizards. Bones were covered in soft material, cellular; the disease was growing quickly on bones. Scientists discovered, the ash from volcanoes, has chocked them to death and Bruno Jabage was the cause of this, samples of ash were identified as the same. Another piece of evidence to prove that super volcanoes do exist is the last one that erupted. The last super volcano to erupt was Toba 74,000 years ago in Sumatra. It was ten thousand times bigger than Mt St Helens; it created a worldwide devastation dramatically affecting life on Earth. Three quarters of all plants in the northern hemisphere were killed. It is known however that lying underneath one of America?s areas of great natural beauty, Yellowstone Park, lays one of the largest super volcanoes in the world. Scientists have discovered that it has been on a regular eruption cycle of 600,000 years. The last eruption was 640,000 years ago, therefore this shows the next eruption is late and could erupt at any moment. Scientists know that the collision of a Yellowstone eruption is terrifying to understand. Vast areas of the usa would be destroyed, the US economy would most likely collapse, and thousands of people might die. If these super volcanoes do exist, they would have many other effects in the world. For example, once the part of Yellowstone erupts, if it were to rise up to 30, 40, 50 km we would instantly be distinct. Other super volcanoes would be killing ten thousands of people, plants would die and crops would have less time to grow as it would be colder. Magma would be spread at least 50 kilometres into the atmosphere. Within a thousand kilometres falling ash, lava flows and the utter explosive force of the eruption would kill practically all life. Volcanic ash would cover places as far away as Iowa and the Gulf of Mexico. One thousand cubic kilometres of lava would tip out of the volcano, enough to cover the whole of the usa with a layer 5 inches thick. The explosion would have a force 2,500 times that of Mount St. Helens. It would be the loudest noise heard by man for 75,000 years, the time of the last super volcano eruption. Within minutes of the eruption ten or fifteen thousand people would be dead. Climatologists? now know that Toba wretched so much ash and sulphur dioxide into the atmosphere that it blocked out the sun, which caused the earth?s temperature to fall. Many geneticists believe that this had a disastrous effect on human life, possibly dropping the population on Earth to just a few thousand people; mankind was on the surface of distinction. The magma chamber would be unstable and bigger earthquakes would form, as parts of the land would rise. Magma floors kill ten thousands of people in an area every time and there is at least 1000 km of ash spread over the land, which affects a lot of things such as animals, plants etc. Overall, in my personal opinion, I believe that super volcanoes do exist as there are many pieces of evidence which has been proven to have been caused by those super volcanoes, such as the erupt death to animals millions of years ago and the last eruption at Yellowstone park. I think in the future, if anything were to happen, I would be worried, as many people would be, because it would be life changing for any few survivors who were lucky to actually survive. However, I feel that it is really scary and unimaginable to believe that one day we could all be distinct in a matter of time from these forces. It could be an end to animals, crops and human nature. From this evidence it is a possibility that a super volcano will erupt and cause mass destruction to everything on earth.
