Plural volcanoes‚ or volcanos‚ any vent in the crust of the Earth or other planet or satellite‚ from which issue molten rock‚ pyroclastic debris‚ and steam. Volcanism (vulcanism) is the name given to the processes and phenomena associated with the surficial discharge of such material from volcanoes‚ geysers‚ and fumaroles. Volcanoes figure prominently in the mythology of many peoples who have learned to live with eruptions‚ but science was late in recognizing the important roleof volcanism in

Me and My Volcano Volcanoes exist all around the world. There are three types of volcanoes‚ they are shield volcano‚ cinder cone volcano and a composite volcano. A volcano is a place where ash‚ gases‚ and molten material rock from deep underground erupt to the surface. Lava comes out of a vent ‚ then it turns into a lava flow. When external waters‚ such as groundwater ‚ mixes with magma and then it turns into steam. The violence of an eruption depends on the amount of gas that was dissolved

the “scientific study of the origin‚ history and structure of the earth”. It involves understanding earth’s processes‚ materials and its effects on all forms of life. From earth elements such as rocks and mountains to natural phenomenon such as volcanoes and earthquakes‚ the field of geology encompasses a wide range of concepts fundamental to many professions and to civilization in general. Scientific disciplines such as civil engineering and environmental sciences‚ for instance‚ rely on a deeper

Melanie Brooke Yeakley 1. What is the myth from which volcanoes get their name? •It comes from the little island of Vulcano in the Mediterranean Sea off Sicily. Centuries ago‚ the people living in this area believed that Vulcano was the chimney of the forge of Vulcan--the blacksmith of the Roman gods. They thought that the hot lava fragments and clouds of dust erupting from Vulcano came from Vulcan’s forge as he beat out thunderbolts for Jupiter‚ king of the gods‚ and weapons for Mars‚ the god

differences between the material erupted by these volcanoes. Volcanic eruptions are caused by a red-hot liquid rock‚ called magma inside the earth’s core. Volcanoes erupt when magma rises to the surface of the earth‚ which causes bubbles of gas to appear in it. This gas can cause pressure to build up in the mountain‚ and it eventually explodes. When the magma bursts out of the earth‚ it is called lava. The type of magma in the earth can create different volcanoes. If the magma is quite thin‚ the gas can

Philippines also suffered $550 million USD in damage. Volcanic eruptions are the Earth’s most powerful and destructive forces. An eruption begins when pressure on a magma chamber forces magma up through the volcano’s vents. The explosion of Mount Tambora‚ which is still active‚ is one of the tallest peaks in the Indonesian

once. Cinder cones may form as flank vents on larger volcanoes‚ or occur on their own. Parícutin in Mexico and Sunset Crater in Arizona are examples of cinder cones. In New Mexico‚ Caja del Rio is a volcanic field of over 60 cinder cones. Based on satellite images it was suggested that cinder cones might occur on other terrestrial bodies in the Solar system too; on the surface of Mars and Moon.[3][4][5] Stratovolcanoes (composite volcanoes) Cross-section through a stratovolcano (vertical scale

drop as liquid but as a circular or oval cone. Other kinds of Volcanos include a shield volcano that is typically large and has slow flowing liquid lava and a composite volcano. Composit volcanoes are steep and large and have layers from past eruptions that are made of lava. Wizard Island was created when Mt. Mazma‚ a ancient volcano‚ erupted violently approximately 7000years ago lasting months. The eruption is told to be 42 times as powerful as the 1980 eruption of Mount St. Helens and the basin
