This writing will define and discuss the electrical outlethole to overawe: types of volcanoes, body- castation of a volcano, and elements of a volcano; such as, lava, jarful fragments, and gas. This paper also tells a little bit slightly volcanic activity in different parts of the world. What is a volcano?                 A volcano is a vent in the ground from which molten jar and gas erupt. The molten totter that erupts from the volcano forms a mound or mountain much or less the vent. The lava may flow out as a unenviable liquid or it may explode from the vent as solid or liquid particles. Kinds of Volcanic Materials         trey rudimentary 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 hot and may have temperatures of untold 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. extremely 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 volumed areas of Hawaii, where the terms originated. The stickiest lava forms flows of boulder s and rubble called block flows. It may also! form mounds of lava called domes. Â Â Â Â Â Â Â Â Other lava formations are spatter cones and lava tubes. sputtering cones are take over hills that can get up to one hundred feet high. They build up from the spatter of geyser-like eruptions of thick lava. Lava tubes are tunnels formed from quiet lava. As the lava flows, its exterior covering cools and hardens. But the lava below continues to... If you indigence to get a full essay, order it on our website:
