A lot of them have made this world at times a whole lot of disasters and left plenty of people dead. Some volcanos even wiped out whole cities and towns. Here in the wonderful United States lies stands just about 169 active volcanos and about half of them are very threatening to the people of our country. Throughout the past couple of years, a couple of these volcanos have erupted. But it won’t be the only time they erupt. Most of them are expected to erupt sometime in the next couple decades. A volcano is an opening or rupture in the earth’s crust that allows hot lava, volcanic ash, and gases to escape from the magma chamber below the earth surface. To make it a little bit easier for you to understand, when pressure is built up somewhere, it has to get out. The only way for pressure from beneath the earth’s surface to go is up, which would be through a volcano eruption. In the world, we have four types of volcanoes that we pay attention to the most.

  • Rainier Vs Yellowstone Research Paper

    860 Words  | 2 Pages

    What is a super volcano, what is a volcano? A volcano itself is a hill or mountain with vents to the crusts of the earth that let magma sit under or in the mountain. “A super volcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. Super volcanos are on a much bigger scale than other volcanoes. Unlike composite volcanoes, with their steep sides, they are difficult to spot.” (Internet Geography, geography.learnontheinternet.co.uk) An average volcano in the world would just cause local damage, but this super volcano could end life on earth. Not just with the eruption but the ash would cause a volcanic winter blocking the sun to long and then even more the ash would choke everything out and collapse roofs. Yea Rainier would kill thousands of people, but Yellowstone would literally kill billions plus of people. In comparison, Rainier is a little fly and Yellowstone is a Griffin {The big eagle lion bird thing}. Yellowstone has the capability to erupt 1,000 times stronger than Rainier ever could.

  • Triangle Fire Essay

    Disasters can be so impactful; some can forever change the course of history. While many at the time thought this story would soon pass, and with it all the potential bad publicity, the story of the Triangle fire spread quickly, and outraged many people. On a beautiful spring day in March 1911 when 146 workers lost their lives, a fire would prove it could do what years of reformers had failed to do, get the government on the side of the workers. I would argue that the fire largely impacted the country. Specifically, the Triangle Fire ended up changing New York’s interconnected political and economic scene, and spurred on the creation of stricter safety codes. For the first time owners would hold responsibility for their actions. Max Blanck and Isaac Harris; being indicted for manslaughter was proof of this. Social change seemed to be spurred as well; the general public and newspapers would come back the workers of New York. Large institutions would suffer as well. Tammany Hall would be feared less and less by waves of new immigrants. The largest change brought about by the blaze would be legislation. Twenty-five bills, recasting the labor laws of the state

    The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.

As populations continue to increase and more people are attracted to the beauty surrounding these areas, the immediate threat to humans from these sometimes sleeping giants grows.

    Igneous rocks are formed from the ejection of earth’s volcanoes. Deep down inside earth’s mantle there lies hot magma. Magma is molten rock that is kept below the surface. This mixture is usually made up of four parts: a hot liquid substance which is called the melt; minerals that have been crystallized by the melt; solid rocks that have made themselves tangled in the melt because of loose materials, and finally gases that have become liquid. Magma is created by an increase in temperatures, pressure change, and a alter in composition. When this magma is ejected from earth’s crust it earns a new name called lava. The lava hardens and becomes an Igneous rock.
