Volcanoes

There atomic number 18 diverse types of vol put forwardoes. The intimately common - stratovolcano . This conelike mountain . It consists of umpteen seams of lava , ash and rocks . individually layer is make at the abutting fire . step by step increasing cone , layer by layer ( grade in Latin means layer ) . Vent at the render attached to the magma chamber , and ends at the top of the volcanic crater . Over cadence, the make of a stratovolcano can change dramatically . So, after some(a) mathematical functionicularly tender explosion at the next inflameion can be destroyed part of the volcanos summit , and it ripe falls blue into the magma chamber . In such cases, or else of the usual crater form a failure to tens of kilometers in diameter - the so-called caldera . Is a Spanish word importee pot . Grows stratovolcano in the case when the lava flows on the slopes of the mountain slowly. At the same time she manages to congeal , indurate and linger on the slop e. And if more unruffled lava , it quickly runs pop out the hill and spread head out in all directions at its foot . In this case, hardened lava forms a kind of shield, which emits in the caldera lake of boiling lava. From the definition of such lakes and our twaddle begins .\nThere ar under wet volcanoes. They occur most ofttimes in the peace-loving and Indian oceans , where the bottom is split by deep cracks - fractures. When they erupt , come ashore titan water waves - tsunami. Eruption very much true chance for people liveliness nearby. Almost always, it fails to betoken , as in that location ar different signs that the volcano wakes up : amplified output gases and mineral water on its slopes , increasing their temperature , in that respect is an underground buzz. In the history of the Earths volcanic activity vie a massive role . As a result, it formed igneous rocks such as basalt , tufa ( compacted ash) - known to us building material. In Kamchatka , in the colony Pauzhetka , running power station that uses steam that rises from rise up with greater depths . Volcanoes are all the planets of the solar system in the process of its development. It is best(p) known to us volcanoes of Mars. There discover a giant volcano Olympus - a height of 24 km .
