Volcano: A hill or mountain formed around and above a vent by accumulations of erupted materials, such as ash, pumice, cinders or lava-flow. The term refers both to the vent itself and to the often cone-shaped accumulation above it. (Scarth, 1994.) This definition can do Mt. Vesuvius no justice. Instead, I would describe it as one of the most hellish and population decimating volcanoes. Vesuvius lives or lived! In its prime, Vesuvius covered and demolished two of Italy's biggest cultural and artistic cities of its time. In this paper, I will be discussing volcanoes in general. In addition, Mt. Vesuvius, in particular, will be thoroughly looked at, as well as its 79 AD eruption.
Volcanoes have long been depicted as nature's killer. In movies, Volcanoes are seen as mountains of fire and spitting lava; their only purpose seems to be to kill and destroy everything in their path. Never is the background of volcanoes discussed. How are volcanoes formed? Are there different types of volcanoes? What happens during an eruption? The basic questions to aid understanding of volcanoes might change the public's opinion. .
First, I will begin with the creation of volcanoes. Volcanoes are formed in different ways. In a short version: the earth's plates shift and move. After the plates collide into each other, one plate is pushed down into the mantel below the crust and melts. Hot magma from the mantle breaks through a weak spot in the crust. As the .

magma shoots out of the crust, the cooling magma called lava becomes hard. After significant time, the hard lava forms a volcanic mountain. Volcanoes can form in many different sizes and shapes. They can look like a cone, have steep looking flanks, or look as if they were long cracks in the earth's crust. (Plummer et al., 2000). If the mountain is very tall, then there is a greater chance that it was formed from past eruptions. When the lava cools, it makes the mountain bigger and higher.
These are words that most people associate with volcanoes. But some good effects can come out of volcanoes. ... Out of the 550 of the world's active volcanoes, the world's largest active volcano is Mauna Loa, it is one of the Hawaiian islands. ... Then there are underwater volcanoes and above ground volcanoes. ... This is the only volcano found on the planet mars. ...

The term volcano refers to the opening or vent through which the molten rock and associated gases are expelled. ... Instead, volcanoes are built by the accumulation of their own eruptive products. ... Geologists have generally grouped volcanoes into four main kinds: cinder cones, composite volcanoes, shield volcanoes, and lava domes. ... When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt(explode). ... With many volcanoes erupting only every few hundred or thousand years, it's not possible to monitor every site. ...
This report features what are volcanoes, how are they formed and where are they located. It also has a recent occurrence of a volcano eruption and how did the community react to it. Volcanoes are mountains formed out of lava and ashes through an opening in the earths crust. ... After many eruptions volcanoes expand. There are two ways that volcanoes are formed. ...
Some of the most famous composite volcanoes include Mount St. ... At 6,893 meters in elevation, not only is it the highest active volcano in the world, but Ojos del Salado is the highest active volcano in Chile and the second highest active volcano in the Southern and Western Hemispheres. ... The Mayon Volcano is 2,462 meters in elevation and is a symmetrical composite volcano. ... Another harsh eruption from the Mayon Volcano was in 1993. ... Interesting facts such as how high a volcano's elevation is or how many deaths it caused makes a volcano well-known to the public eye. ...
A volcano can erupt many times in its lifetime. ... There are three major types of volcanoes, cinder cone volcanoes, composite volcanoes, and shield volcanoes. ... The second major type of volcano, the composite volcano, in contrast to the cinder cone can grow much larger. One famous example of a composite volcano is Mt. ... The third type of volcano is the shield volcano. ...
Volcanoes A volcano is a vent in the earth's crust through which magma (molten rock) and gas are released. ... Types of Volcanoes There are three different types of volcanoes that can be formed around a vent. ... Since these volcanoes consist of loose materials they do not grow as large as other volcanoes. ... The third type of volcano is the composite volcano. ... I then molded a volcano shape out of the clay. ...
This cone is what we know as a volcano. There are several ways in which a volcano can form, just as there are several different kinds of volcanoes. Among the different kinds of volcanoes are shield volcanoes, cinder cones, and composite volcanoes. The most majestic of the volcanoes are composite volcanoes, also known as strato-volcanoes. ... There are two types of shield volcanoes, Hawaiian volcanoes and Icelandic. ...
Some volcanoes are more active than others. ... Fuji are all examples of strata volcanos. Shield volcanoes are made of thousands of thin lava flows. ... Shield volcanoes are the largest volcanoes. ... After this, hot springs may form from the volcano. eventually volcanic heat will disappear, and cool water will issue from the volcano and the ground in it's vicinity. ...
