metamorphosed the original rock producing the Pedler gneiss and Old Rag granite which can be observed in the Shenandoah National Park. In late Precambrian time this super continent began to rift apart under the tensional forces producing the Catoctin rift basalts that can be observed in the Shenandoah. As they rifted apart‚ they created a growing ocean called the proto-Atlantic or Iapetus after the father of Atlas‚ for whom the Atlantic Ocean is named. Towards the end of the Precambrian‚ the tensional forces

Beyond Realism “Artists deliberately set out to provoke audience reactions.” The purpose of this essay is to argue how “Artists deliberately set out to provoke audience reactions”. The essay will explain how artists have used abstraction‚ stylisation and distortion in artworks through the ages through the analysis of Robert Smithson’s “Spiral Jetty” and Colin Lanceley’s “Night Garden”. This essay will discuss‚ compare and analyse the development and evolution of abstract art. “Abstract art can

Volcanism‚ the name given to volcanic processes‚ really has shaped the world. Eruptions have rifted continents‚ raised mountain chains‚ constructed islands and shaped the topography of the earth. The entire ocean floor has a basement of volcanic basalt. Volcanoes have not only made the continents‚ they are also thought to have made the world’s first stable atmosphere and pro vided all the water for the oceans‚ rivers and icecaps. There are now about 600 active volcanoes. Every year they add two

produced by mantle upwelling and a shallow melting zone. This new magma is the first phase of the igneous part of the cycle. The types of igneous rocks are Granite‚ Pumice‚ Obsidian‚ Andesite‚ Rhyolite and Basalt. There are large amounts of Rhyolite found in Taupo and Rangitoto Island is made of Basalt. The transition to metamorphic is when sedimentary or igneous rocks change in structure and appearance by the exposure of high temperatures and pressure over time. As the oceanic crust is pulled back

Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description | |Andesite |Extrusive |Usually blackish-brown‚ sometimes greenish. Papier-mache look.Contains less than 5% quartz. | |Basalt |Extrusive |Very dark‚ often black. Often contains phenocrysts of feldspars

Mass extinction; This is a term that most don’t fully appreciate the severity of. Like many aspects in the time scale of our earth and solar system‚ it is difficult to comprehend its scale at the surface. A mass extinction is classified as a massive dying of animal species in a short geologic window. In the above analogy that would mean having anywhere from 70% to 90% of creature species die in a fraction of a second. Mass extinctions are driven by a compounding of events. For example‚ the extinction

GEOLOGY & CIVIL ENGINEERING As living creatures‚ the importance of understanding the earth we live in is paramount for our survival and development. Geology is the “scientific study of the origin‚ history and structure of the earth”. It involves understanding earth’s processes‚ materials and its effects on all forms of life. From earth elements such as rocks and mountains to natural phenomenon such as volcanoes and earthquakes‚ the field of geology encompasses a wide range of concepts fundamental
