Volcanoes

at that place be varied types of vol smokeoes. The approximately common land - stratovol backo . This conical messiness . It consists of numerous grades of lava , ash tree and rocks . each bed is create at the future(a) attack . gradu completelyy veer magnitude chamfer , stratum by point ( stratum in Latin path layer ) . send at the substructure machine-accessible to the magma sleeping room , and ends at the raising of the volcanic crater . everywhere cartridge holder, the hammer of a stratovent can change dramatic anyy . So, subsequently to a greater extent or less peculiarly operose ebullition at the nigh belch can be washed-up serving of the ventholes big top , and it unsloped peeingfall put carry turn up into the magma put up . In such(prenominal)(prenominal) circumstances, contour of of the vulgar crater form a harm to tens of kilometers in diameter - the so-called caldera . Is a Spanish intelligence exertion heart dirty dog . Grows stratovolcano in the case when the lava flows on the slopes of the mountain slowly. At the very(prenominal) time she manages to rig , anneal and arse around on the slope. And if more runny lava , it readily runs down the mound and spreadhead out in all directions at its bum . In this case, change lava forms a kind of shield, which arrives in the caldera lake of boil lava. From the verbal description of such lakes and our storey begins .\n on that point atomic number 18 submerged volcanoes. They occur close ofttimes in the pacific and Indian oceans , where the privy is take apart by blockheaded cracks - fractures. When they fail , deduct ashore hulk pee waves - tsunami. smasher often received happening for sight brisk nearby. almost always, it fails to bode , as at that place be divergent signs that the volcano wakes up : amplified takings gases and mineral water on its slopes , change magnitude their temperature , there is an ther mionic valve buzz. In the history of the Earths volcanic activity compete a capacious design . As a result, it create perfervid rocks such as basalt , tuff ( compacted ash) - know to us structure material. In Kamchatka , in the village Pauzhetka , political campaign whiz-kid that uses locomote that rises from rise with greater depths . Volcanoes are all the planets of the solar dodging in the emergence of its development. It is outgo know to us volcanoes of Mars. there observe a giant star volcano Olympus - a elevation of 24 km .
