Volcano were proposed for volcano behavior before the modern understanding of the Earth's mantle structure as a semisolid material was developed. For decades after awareness that compression and radioactive materials may be heat sources, their contributions were specifically discounted. Volcanic action was often attributed to chemical reactions and a thin layer of molten rock near the surface. Volcano A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major,
Volcano: The Blast Coaster Volcano: The Blast Coaster Volcano: The Blast Coaster (often shortened to Volcano) is a launched inverted roller coaster at Kings Dominion in Doswell, Virginia. Designed by Werner Stengel and built by Intamin, Volcano was the world's first inverted roller coaster to feature an linear induction motor (LIM) and is the only one of its kind that completes a full circuit. The roller coaster opened to the public on August 3, 1998. A portion of the ride is enclosed inside a man-made Volcano. Volcano was designed around a dormant attraction originally known as The Lost World, and later as Smurf Mountain.
