Oceanic crust

elongated belts of folded and thrusted faults in marine sedimentary rocks. Convection cells in the Earth’s mantle drove the movement of tectonic plates to form the basin. The North American continent sits on the oceanic crust, which explains the tectonic plate movement throughout the crust. The Appalachian region is a plate margin and has periodically submerged beneath shallow seas (Galey, 1948). Upwelling is the definition of a rise in seawater. Plate margins are the layers covering the…

island, Hawaii. Also, a new volcano, Loihi, has formed off the southeastern coast of the island of Hawaii and Loihi appears to follow the trend of volcano formation in the chain – with the more recently formed volcanoes breaking through the earth’s crust and building up to form the archipelago from the oldest in the northwest and descending toward the southeast where the two most recently active volcanoes in the chain, Mauna Lea and Kilauea are located.…

The element silver (ag) is named from the Anglo-Saxon word seolfor, it’s chemical symbol, Ag, comes from the Latin word argentum, derived from the Greek ὰργὀς (are-ah-gush). This name comes from a Proto-Indo-European language root. Silver has been around for thousands of years, with many versatile uses. From a scientific layout, silver has an atomic weight of 107.8682, contains 47 protons and electrons respectively, and has 61 neurons. This element has a melting point of 1234.93 K (961.78 °C…

islands for size, development, and economy. The eight major islands that make up the state of Hawaii are Hawaii, Kauai, Oahu, Molokai, Lanai, Maui, Niihau, and Kahoolawe. The islands are located on a geothermal hot spot. This is where the earth’s crust is thin, so shield volcanoes easily develop…

6th BIOLOGICAL CRISIS WHICH MAN IS THE CAUSE ABSTRACT This article will discuss the biological crises the Earth faced since the creation of the living organisms. Then, this article will argue the reasons why human beings generated a 6th biological crisis. Finally, this article will explain what the elements of this 6th biological crisis are. KEYWORDS Biological crisis, Extinction of species, environmental ecosystems, massive extinction, ecological niches, Industrial Era, greenhouses gases,…

The distribution of events with magnitude M ≥5.5 is not uniform across the continent. Geologic Setting The continent of Australian is flank on its southern, eastern and western, edges by oceanic layer, which started to frame at c. 155 – 165 Ma (Stagg et al., 1999; Müller et al., 2000). The spreading of Seafloor stopped at c. 55 Ma, aside from in the south where Australia keeps on moving north far from Antarctica. Toward the north, a Tertiary…

abnormal man-woman relationship have been portrayed with a remarkable poignancy. Sita is married woman and has four children, but in the very picture of misery and dejection. She feels herself to be a prisoner in a house which offers her nothing but a crust of dull tedium, of hopeless disappointment. Her unhappiness in married life finds expression in feelings of contempt for the friends and colleagues of her husband. After unpacking her things and lying down with her children, Sita ruminates…

and this implies that few people believe that the undertaking will yield guaranteed results. Additionally, this mission is not the first attempt to reach the Earth’s Mantle, as a team of US scientists managed to drill a few meters into to the oceanic crust off Guadalupe Island in 1960, however were not successful. Moreover, the text stated, “…the project did not get much support after his demise and was shut down in 1966…whilst in 2011, oil giant Exxon Mobil managed to go just slightly beyond…

December 26th, 2004 marks the day a 9.1-9.3 magnitude earthquake triggered arguably the deadliest tsunami of the twenty-first century. The 1,300 km fault zone spawned a wave reaching fifty meters in height and five meters inland. Fourteen countries worldwide lost an estimated 230,000 people [Geist et al., 2015] and a devastating ten billion dollars to the colossal Indian Ocean swell. The devastation kick started efforts to create better technology and innovations so that when the next disaster…

many active fault zones within the Earth (Fronabarger). Most earthquakes are made along faults, tectonic plate boundary zones, or even along mid-oceanic ridges (Pidwirny). Small earthquakes can be caused by volcanic activity, landslides, mine blasts, and nuclear experiments (Science Daily). Sun and moon cause tremors by creating tides in Earth 's crust (Live Science Staff). When plates squeeze or stretch, huge rocks shift making faults and causing earthquakes ("Earthquakes"). Faults are where…
