what and where is the "ring of fire"?
957674
The Pacific Ring of Fire is a zone of frequent earthquakes and volcanic eruptions encircling the basin of the Pacific Ocean. In a 40,000 km horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, island arcs, and volcanic mountain ranges and/or plate movements. It is sometimes called the circum-Pacific belt or the circum-Pacific seismic belt.\n\n90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire. The next most seismic region (5–6% of earthquakes and 17% of the world's largest earthquakes) is the Alpide belt which extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. The Mid-Atlantic Ridge is the third most prominent earthquake belt.

1.the molten mixture of rock-forming subtances, gases,and water deep in earths mantleis called magma .\n2.the ring of fire is a belt of volcanoes around the rim of the pacific ocean.\n3.the more Silica that the magma contains, the thicker the magma is.\n4.An eruption happens when an explosive erruption hurls ash,cinder,bombs,and gases out of a volcano. \n5.in a process called smeltin, an ore is melted to separate the use full metal from other elements from the ore.\n6.the property of density is the mass of the minral sample per unit volume.

Under the continents.  The term refers to the basaultic shields on which the continents "float" on the magma underneath.  When they shift and grind against one another, we have volcanoes and earthquakes.

there are three, right?\n\n    * Yellowstone Caldera, Wyoming, United States - 2.2 million years ago (2500 km³) and 640,000 years ago (1000 km³)\n    * La Garita Caldera, Colorado, United States - 27.8 million years ago (over 5,000 km³)\n    * Bruneau-Jarbidge, Idaho, United States - 10-12 million years ago (responsible for the Ashfall Fossil Beds 1600 km to the east)\n\n I got that from Wikipedia:http://en.wikipedia.org/wiki/Supervolcano\n\nAm I right?  Come back and tell me, please.

Indonesia has the most volcanoes, by far. It is really a special place because there seem to be volcanoes all around, in all directions. Merapi (which means "mountain of fire") erupted in January 1994 and killed a few hundred people.

the activity, located between the aleutian islands and southern japan, is importent in huge ways. you know how the earth contains a lot of pressure? well, the ring of fire acts as a waste basket because the earth gets rid of the pressure by using the volcanos. another importent thing is the magma. the magma, combined with water, metals, rock and heat, are used to create islands.

I'd start with the NAFAA (North American Fire Arts Association). If you happen to be in the right area, the crucible and the burning man festival may be useful too.

I don't know, but it's apparently somewhere in Australia..\n\nCheck this out:\nhttp://www.gnomon.com.au/publications/bsd/990116.shtml

the opening is called the vent,the answer you probably want is the crater as that is the part above ground which you see(big hole).the vent is a gap in the rocks beneath the crater through which the magma passes up from the eruption chamber.

I'm pretty sure it's Iceland. I lived there for a while and remember hearing something about that.

Curiously, I could not find a comprehensive listing.  This site might be helpful, however, or at least give you a start.\n\nhttp://dir.yahoo.com/Science/Earth_Sciences/Geology_and_Geophysics/Volcanology/Volcanoes

Most earthquake happens around the edge of the Pacific Ocean. Namely Japan, Alaska, California, etc. Its been called the Ring of Fire, because numerous volcano eruptions have been caused by earthquakes in these areas. The cause of the earthquake is due to the movement of 2 or more underground plates rubbing against each other either in a vertical or horizontal movement. Usually these movement goes smoothly without anyone noticing, but when a big shift - slippage occur we observe this as a major earthquake. Just like rubbing your hands together, most of the time it will go smoothly, but once in a while you will catch and cause a big jerk.

Iam not an American, but I think I am correct in saying that Mount Lassen is still an active  volcano,  it stays quiet for a number of years and then without warning it has a massive expulsion.I do know it is in a National Park and in an area of outstanding beauty.

The "Ring of Fire" is an arc stretching from New Zealand, along the eastern edge of Asia, north across the Aleutian Islands of Alaska, and south along the coast of North and South America. It is composed over 75% of the world's active and dormant volcanoes.\n\nThis huge ring of volcanic and seismic (earthquake) activity was noticed and described before the invention of the theory of plate tectonics theory. We now know that the Ring of Fire is located at the borders of the Pacific Plate and other major tectonic plates.\n\nPlates are like giant rafts of the earth's surface which often slide next to, collide with, and are forced underneath other plates.\n\nAround the Ring of Fire, the Pacific Plate is colliding with and sliding underneath other plates. This process is known as subduction and the volcanically and seismically active area nearby is known as a subduction zone. There is a tremendous amount of energy created by these plates and they easily melt rock into magma, which rises to the surface as lava and forms volcanoes.\nVolcanoes are temporary features on the earth's surface and there are currently about 1500 active volcanoes in the world. About ten percent of these are located in the United States.\n\nThis is a listing of major volcanic areas in the Ring of Fire:\n\n1. In South America the Nazca plate is colliding with the South American plate. This has created the Andes and volcanoes such as Cotopaxi and Azul.\n\n2. In Central America, the tiny Cocos plate is crashing into the North American plate and is therefore responsible for the Mexican volcanoes of Popocatepetl and Paricutun (which rose up from a cornfield in 1943 and became a instant mountains).\n\n3. Between Northern California and British Columbia, the Pacific, Juan de Fuca, and Gorda plates have built the Cascades and the infamous Mount Saint Helens, which erupted in 1980.\n\n4. Alaska's Aleutian Islands are growing as the Pacific plate hits the North American plate. The deep Aleutian Trench has been created at the subduction zone with a maximum depth of 25,194 feet (7679 meters).\n\n5. From Russia's Kamchatka Peninsula to Japan, the subduction of the Pacific plate under the Eurasian plate is responsible for Japanese islands and volcanoes (such as Mt. Fuji).\n\n6. The final section of the Ring of Fire exists where the Indo-Australian plate subducts under the Pacific plate and has created volcanoes in the New Guinea and Micronesian areas. Near New Zealand, the Pacific Plate slides under the Indo-Australian plate.

The above anwer is nonsense if you are talking about the Devil's Tower in Wyoming inside Devil's Tower National Park. Devil's Tower is not believed to have ever erupted. \n\nThat Devil's Tower (the only other one I know of is in Illinois) was an igneous intrusion. Molten magma pushed upward into sedimentary rock about 65 million years ago and cooled forming Devil's Tower. While it is still possible that it was part of a volcano, there has been no evidence found that it ever broke through the surface and erupted. It was not exposed until many millions of years later the sediment around it eroded away. \n\nAt the website below there is an animated illustration of how the tower formed and was uncovered by erosion. \nhttp://www.nps.gov/deto/geology.htm

hey it sounds interesting but where it is ? let me know plz
