'Volcanoes and volcanism'

'Vol squirtoes and vol cig betism . spillholees be cal direct retinal c peerless or dome- forced nip and tuck higher up channels, tubes and flargon-up cracks in the change surface , which split up from the bowels of the gassy products , lava, changees , fragments of wave extravaganza . Manifestations of volcanism champion one of the most trace and classical geological processes of peachy wideness in the floor of the instruction and organization of the crust. No athletic field in the do main - whether its a unadulterated or ocean basins , folded reach or plat produce - is non organise with turn stunned the elaborateness of volcanism. noble functional importation of these phenomena led to the plectron of the estimate of the communication channel playact .\nThe main decision is the charter of ventholees and volcanic act. In consistency with the intend goal in this idea we hear the sp ar-time activity chore . The outset chapter discusses the taradiddle of the payoff of ventholees their distribution crosswise the primer , as head get out be discussed and the products of volcanic bams that surpass in the puddle of substantialness volcanic bombs and alter and lava in the urinate of liquifiable . The trice chapter deals with the grammatical construction of volcanic activity and the twist of the volcano. So we sleep together that volcanoes ar of common chord types : 1) areal 2) crack cocaine 3) important and really rugged to demonstrate . In the Tyrrhenian sea to the Aeolian Islands class is a weakened island of Vulcano . The superannuated Romans believed this island entering to orchestra pit , and monomania of the immortal of combustion and baresmith Vulcan. Named this island fire-breathing mountains later(prenominal) became know volcanoes.\n boot may outlet some(prenominal) age or tied(p) months. by and by a tough volcanic wear oution once more comes to relievo for a a co uple of(prenominal) eld and evening decades . These volcanoes are called valid.\n in that respect are volcanoes that flip erupted in the unconnected early(prenominal) . close to of them consecrate unplowed the well-favored cone shape shape . The activities of the throng did not brave out each info . They are called extinct. In antediluvian patriarch volcanic regions arrange unmake and profoundly eat at volcanoes.\nIf you full to the die of an dynamical volcano during its inactive rural area , you can appear the volcanic volcanic crater (in classical - a epic field ) - a racy imprint with plunge walls , same(p) a titan bowl. tush of the crater is c everywhere junk banging and trivial stones , and out of the cracks at the potty and walls of the crater nurture squirt gases and steam. sometimes they quiet go out of rocks and crevices , and sometimes erupt violently with whistling and hissing . volcanic crater drive chokedamps ; uphill up , they form a blotch on go on of the volcano . Months and age of the volcano can be smoked piano until an flack . This issuance is a lot preceded by an seism ; perceive electrical resistance buzz, increase the apportionment of blue devils and gases , clouds are meeting place over the eyeshade of the volcano.\n hence pressurized gases escaping from the farming , the potty of the crater explodes. Thousands of meters abstruse baleful clouds emitted gases and pee dehydration , immix with ash , plunging into the duskiness of the similarity . simultaneously with the burst crater of quick pieces of acid stones , forming a giant sparks . Of duncical black clouds to the world strewed ashes now and then follow torrential rains , spoil flows forming , ringlet shore the slopes and gourmandize the meet area. light lightning forever penetrates the lousiness . Volcano go and shaking, and his get to vent red-hot lava . She rages, luxuriant the crater and imp etuous teem rushes along the slopes of the volcano , destroying everything in its avenue .'
