" The source of atmosphere "
Besides the danger of the volcano, the volcano was also a producer of Atmosphere . Atmosphere that exists on earth, has been created since tens of millions of years ago. Although experts do not know the exact cause of the emergence of Atmosphere, but the suspicion towards the volcanic emissions.
Ten millions years ago, there are thousands of volcanoes on earth. They broke out in turn. Of the eruption, volcanic gas emissions there. Emissions of volcanic gas contains hydrogen, carbon monoxide, halocarbons , organic compounds, and metal chlorides. While the oxygen and carbon dioxide in the Atmosphere may be derived from living things of the earth. All these things are the material contained in the Atmosphere at this time. However, scientists do not yet ensure that it is correct.

" Most killing volcanic eruption in the world - The eruption of Moun Tambora "
Mount Tambora, is an active stratovolcano located in the island of Sumbawa, Indonesia. Mount Tambora was once the tallest peak in the archipelago and the magma chamber could dry up the mountain and it took a century to restore the mountain's magma chamber.
Mount Tambora erupts in April 1815. The eruption of Tambora in 1815 that led to 71,000 people have died either directly or indirectly. Height of the eruption of smoke is approximately 43 km.

It is not possible to prevent global warming caused by the volcano. However, there is an odd way to overcome this. Which growing plants. Plant has been ascertained to handle Co2.
" Supervolcano "
| Supervolcano eruption |
Supervolcano is a very large volcano if it erupts it can destroy a big place and even a continent. Eruptions can cause global cooling over the years due to the large volume of sulfur and ash.
Examples of Supervolcano at the Yellowstone caldera in Yellowstone National Park and Valles Caldera in New Mexico. One result of the supervolcano Toba is a lake named Toba lake.
" Olympus Mons - The highest volcano in the universe "
