Since Earth's early days, volcanic eruptions have shaped our planet and now we know they have shaped other planets as well. Volcanic eruptions constitute one of the minor natural disasters on the planet Earth because they cause fewer fatalities than earthquakes and famines (Encyclopedia Britannica). Even though, scientists have estimated that at least 200,000 persons have lost their lives as a result of volcanic eruptions during the last 500 years (Yorkshire Post).
A volcano is a vent in the Earth from which molten rock and gas, erupt from the inside forming a hill or mountain around the vent. There are three different types of volcanoes, active, dormant, or extinct. An active volcano is one that erupts either continually or periodically. There are several active volcanoes in the continental United States: Lassen Peak in Lassen Volcanic National Park (California), Mt. St. Helens in Cascade Range (Washington State), and Mt. Katmai (Alaska) (Yorkshire Post). A volcano that has been known to erupt within modern times but is now inactive is classified as a dormant, or sleeping, volcano. Mt. Rainier (Washington), Mt. Hood (Oregon), and Mt. Shasta (California) are examples of volcanoes in the continental United States (Hale). A volcano not known to have erupted within modern history is classified as an extinct volcano. Although, Volcanologists consider truly extinct volcanoes to be those that have been worn away almost to the level of their magma chamber (Hale). .
An exact number of existent volcanoes is unpredictable, nobody has really counted all of the volcanoes, especially the tens on thousands on the sea floor. In deed, the best guess is 1511 volcanoes have erupted in the last 10,000 years and should be considered active (Simkin & Siebert). .
These eruptions had contributed in many good ways to our planet Earth. The earth's water and atmosphere are evolved from the gases produced by volcanic eruptions, helping to proof human beings life.

These consist of the shield volcanoes, strato (composite) volcanoes, and caldera complex volcanoes. ... It is classified as a complex volcano, so it is an explosive and very steep strato volcano. ...
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. ...

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. ...
