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

        This writing will define and discuss the electrical outlethole to bar: types of volcanoes, operateation of a volcano, and elements of a volcano; such as, lava, jounce fragments, and gas. This paper also tells a little bit close to volcanic activity in different parts of the world. What is a volcano?                  A volcano is a vent in the ground from which molten tilt and gas erupt. The molten totter that erupts from the volcano forms a mound or mountain slightly the vent. The lava may flow out as a gluey liquid or it may explode from the vent as solid or liquid particles. Kinds of Volcanic Materials          trey basic materials that may erupt from a volcano ar; 1. lava, 2. rock fragments, and 3. gas.          Lava                  Lava is the na me for magma that has been released onto the Earths surface. When lava comes to the Earths surface, it is red hot and may have temperatures of a lot than 2012 degrees Fahrenheit. Fluid lava flows swiftly down a volcanos slopes. Sticky lava flows more slowly. As the lava cools, it may harden into many different formations. super 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 sizeable areas of Hawaii, where the terms originated. The stickiest lava forms flows of boulders and rubble called block flows. It may also form mounds of lava called domes.         Â Other lava formations are spatter cones a! nd lava tubes. sputtering cones are suck up hills that can get up to one hundred feet high. They progress to up from the spatter of geyser-like eruptions of thick lava. Lava tubes are tunnels formed from placid lava. As the lava flows, its exterior covering cools and hardens. But the lava below continues to... If you requisite to get a full essay, order it on our website: OrderEssay.net
