A volcano is a mountain or hill built up around a vent that connects to a reservoir of molten rock from beneath the surface of the Earth. The molten rock is lighter than the surrounding hard rock and will eventually break through a weak point in the Earth’s crust. When this happens the volcano may have a violent eruption of gas, rocks, molten lava, and ash. Volcanoes are generally grouped into four categories: cinder cone, composite volcanoes, shield volcanoes, and lava domes.
The Volcanic Eruption of Mount Saint Helens
On the 18th of May 1980 mount saint. Helens Erupted all thought Mount
Saint Helens is a volcano the eruption in 1980 was actually caused by
an earthquake the earthquake was 5.0 on the Richter scale. The tremor
trigged the biggest landslide ever recorded this was due to molten
Mount Saint Helens is part of the Cascade Range which has numerous
volcanoes thought Mount Saint Helens is the most active.

Mount Saint Helens is a volcano located in southwestern Washington. It is 8,363 feet tall. Geologists say that Mount St. (Saint) Helens is a stratovolcano, also known as a composite volcano. Stratovolcano is a volcano that is built upward because of layers of hardened volcanic ash, lava, and other volcanic debris. These kinds of volcanoes are distinguished by their steep sides. They often erupt extremely explosively, putting people and properties nearby at risk.
Earth has physically changed millions of times due to moving tectonic plates which has formed our planets mountains; altering the way our environment looks. Volcanoes, (formed when magma from the upper mantle heads to the surface, causing the land to rise) are one of nature’s finest spectacles. These geographical forces have erupted many times; from small-scale eruptions to cataclysmic ones; making them a force to consider about. Therefore the past is useful in predicting possible future eruptions as in terms of the effects they can have on civilisation, they are unpredictable in what they can produce.
Volcanoes have played a key role in forming the face of the earth as we know it today. Some of the most well known landmarks and locations in the world are volcanoes. From the Hawaiian Islands to Mount Vesuvius, the Earth is populated with hundreds of active and dormant volcanoes. Among these volcanoes there are multiple different types. Stratovolcanoes, the most dangerous type of volcanoes, are built by multiple eruptions over many years. Shield Volcanoes, the largest recognizable volcanoes, are characterized by being short but very broad with low sloping sides. Cinder cones, the most common type of volcano in the world, are composed of large amounts of tephra, or pyroclastic debris. The last type of volcano is supervolcanoes. Supervolcanoes are the largest volcanoes. They also have the highest potential for damage. This paper will discuss these these different types of volcano.
What are volcanoes?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In another definition it is a mountain
That has a passage to the underground molten seas of rocks , when the pressure increases on this molten seas it causes eruption gases and molten rocks shoot up through a hole in the top of the mountain and fill the air with lava fragments .
The 1930-50’s golden era of organized labor is over and has lost the energy it had once had as a unifying factor in the lives of workers in the U.S. There are many factors to this decline, but image is very influential in the creation and influence of unions in two ways: externally and internally. Externally, the union’s ideology and actions attract workers into becoming members of a union and how government responds to a union’s beliefs and actions. Internally, union’s are run democratically, where workers choose who will represent them in negotiations with employers, which should give some benefits to the majority of the workers in the union. Organized crime's infiltration into labor unions has rotted the image of unions who represent workers looking to defend themselves against employers and achieve a stable livelihood. The history of labor and organized crime are undoubtedly linked because at times they would use each other to further their own means: the most famous of these links would have to be on James Hoffa. Organized crime and corrupt union officials influence on unions will still exists and although crackdowns throughout the decades have made some progress I doubt that they will be removed entirely from labor.
first experience with labor organizing came when he was a leading member in a strike against Kroger’s grocery in 1932 . He then became a career labor organizer after he was fired from Kroger’s. Although his role was not as great as the other four members of the leadership in organizing the strike, his ability to convince fellow workers to organize was recognized by those around him and he was invited to join the Local 299 of the Teamsters in Detroit. Hoffa was the poster boy for the hardened worker that fought for better treatment in the workplace.
Myths and legends are everywhere. There are legends of people from long ago, myths of ancient Greeks. There are myths and legends of almost everything, including volcanoes. Myths of their creation, of why they erupt. Myths and legends of various gods controlling their own volcanoes. There is a story for almost every volcano. The amount of legends and myths concerning volcanoes is quite extensive, ranging from Hephaestus to Vulcan and everything in between. It's very interesting to know what people thought of volcanoes when the myths were made; myths about volcano are as captivating as other myths. Take Pele, one of the gods associated to volcanoes I'll be talking about, for example.
Blank. That’s how every canvas should begin. However, the canvas I faced was bleeding with chaos. Ash from volcanic eruptions fought with blades of water beating down, darkening the sky as rubies and citrines spewed from the angry mouths of volcanoes. The once lush, vivid landscape of palm trees, hibiscuses had been blackened to their cores. The earth maniacally bellowed at the havoc entrapping me; my shoes struck the ground, attempting to beat my heart in the race to avoid the sudden dips into oblivion. Thud, my aching feet had betrayed each other as the ground cracked beneath me. “I can’t do this any longer,” I thought, as my eyelids fell along with my body.
