Earthquakes - Research Paper Example As a result, pressure is build up where the plates collide or bend, and the rocks develop cracks or faults that allow them to release the buildup energy, because of the strain. Earthquakes can hence occur at the boundaries or even in middle of the plates, based on where the strain is build up. The paper also gives latest discoveries and unanswered question on how to tell the timing of an earthquake. Keywords: Collide, Earthquakes, Strain, Energy, Boundaries, Magnitude, Seismologists, Seismograph, Faults, Tectonic Plates Introduction Earthquakes are natural disasters that have devastating effects on the environment. They often go unnoticed, and only those with a magnitude capable of being detected are reported or felt on the earth’s surface. According to FEMA, earthquakes are sudden earth shakes or tremors that result from the shifting and breaking of subterranean rocks, as they release accumulated strain build up for a long period (n.d.). It results in immediate effects and th e secondary ones caused by the tremors. Major earthquakes are known to have occurred in Alaska, China, and Japan, but more severe cases are also common along the pacific’s known ring of fire towards the west and south coasts of USA. Millions of lives have been lost, damages worth billions of investment, and aftermath displacement of populations have been recorded over history. Geological Features of Earthquakes To understand the concept of earthquake development, one needs to go back to the study of the earth’s content. The structure of the earth can be categorized into four major components, the inner core (solid part made up of nickel and iron), the outer core (molten nickel and iron), the mantle (third layer from the inside and made up of molten rocks), and the outermost earth’s crust, which has the lightest components of all. The crust is known to host a lot of human welfares and is made up of different types of rocks depending on their origin. The thin laye r of crust and the top of the mantle make most of the earth’s surface. However, they appear as one entity, despite being made up of many entities or pieces to cover the earth surface. These pieces move around and along each other making the earth’s surface to be in a continuous slow motion. The number of pieces and their movement give the impression of pieces in a puzzle. The pieces are the tectonic plates and float on the molten rocks of the mantle. The tectonic plate theory: The entire earth is covered by Lithosphere that comprise of the continental and oceanic plates that are in constant motion. They slide over the uppermost layer of the mantle (plastic aesthenosphere), and end up causing a geological process where they interact, which explains the concept of continental drift and sea floor spreading. The tectonic plates create movements under, over, past, and away, rubbing each other along their boundaries, whose effects are plates interlocking, stretching or bendi ng where they fail to release the accumulated energy (Coppola, 2011). The boundaries of the plates are rough edges and made up of many faults from which the earthquakes initiate. When the plates collide, some of the rough boundaries interlock; the intense pressure may cause the rocks to heat up and bend to create hilly areas, or spontaneous break to form

The Emergence of Modernism Essay Example | Topics and Well Written Essays - 500 words

The Emergence of Modernism - Essay Example All in all, everyone involved needed commitment and dedication towards literary and artistic styles. Latin American artists and writers were encouraged and motivated in the emergence of new literary and artistic styles in the end of the 19th century. Nevertheless, this could not be realized without proper utilization and accommodation to the available factors at that period of time. Industrialization is one of the major contributors towards modernism. The urge by various emerging nations to become industrialized, felt that traditional forms of literature, arts, social organizations, religious activities and their daily lives were becoming outdated (Malcolm and McFarlane 102). Thus, the need for new and modern social, economic, political and environmental conditions was required so as to cater for the emerging markets and increased demands. However, various movement approaches from different artists and writers emerged during this period to make possible towards meeting the rising needs and wants by the industrial world players. Industrialization created room for improvements, devel opment and reshaping of existing forms of literature and arts to the people. On the other end, technology goes hand in hand with modernism. Therefore, technological advancements led to enhanced modernization through democratic revolutions. Technology acted and still acts as a motivating factor in the emergence of new artistic and literally styles. It is through it that we have seen more and increased production of arts and literature. The rate to access raw materials as well as getting them was made easier and comfortable, thus, allowing both artists and writers produce good and quality products. As a result, new methods towards producing new results were realized by the use of different technologies and advancements (Frascina and Charles 142). According to Frascina and Charles (90),
