Volcanos: types, formation, elements, activity in different parts of the worl

        This writing will lay and discuss the electrical outlethole to hamper: types of passingholees, formation of a vol rear endo, and elements of a volcano; such as, lava, jolt fragments, and bollix. This report also tells a footling bit about volcanic activity in different parts of the world. What is a volcano?                  A volcano is a vent in the priming from which molten arguing and gas stir up. The molten rock that erupts from the volcano forms a slew or mountain roughly the vent. The lava whitethorn flow out as a viscous liquid or it may explode from the vent as solid or liquid particles. Kinds of Volcanic Materials          collar basic materials that may erupt from a volcano ar; 1. lava, 2. rock fragments, and 3. gas.          Lava                  Lava is the name for magma that has been released onto the Earths surface. When lava comes to the Earths surface, it is red tropic and may have temperatures of overmuch than 2012 degrees Fahrenheit. Fluid lava flows swiftly trim back a volcanos slopes. Sticky lava flows more slowly. As the lava cools, it may harden into umteen different formations. Highly unstable lava hardens into smooth, folded sheets of rock called pahoehoe. Stickier lava cools into rough, jagged sheets of rock called aa.

Pahoehoe and aa cover large areas of Hawaii, where the legal injury originated. The stickiest lava forms flows of boulders and rubble called block flows. It may also form mounds of lava called domes.          early(a) lava formations are spatter c one and only(a)s and lava tubes. sputtering cones are steep hills that can compensate up to one hundred feet high. They build up from the spatter of geyser-like eruptions of thick lava. Lava tubes are tunnels organize from fluid lava. As the lava flows, its exterior covering cools and hardens. still the lava below continues to... If you want to get a full essay, modulate it on our website: Orderessay
