Comparing 2 different Earthquake Cases Introduction: In this essay I will be comparing 2 different cases of Earthquakes, 1 in an MEDC (More Economically Developed Country) and the other in an LEDC (Less Economically Developed Country) both of a magnitude of 7.0. The two earthquakes that I will be comparing are the Kobe Earthquake in Japan in 1995 of a magnitude of 7 (for the MEDC) and the Haiti Earthquake in 2010 of a magnitude of 7.0 (for the LEDC).I will be comparing the impact after the Earthquake

Controversy surrounds the extinction of the dinosaurs. According to one theory, dinosaurs were slowly driven to extinction by environmental changes linked to the creeping withdrawal of shallow seas from the continents at the end of the dinosaur era. Proponents of this theory propose that dinosaurs dwindled in number and variety over several million years. An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction

The Kangaroo Point cliffs which located below the Main Street River Terrace and the Lower River Terrace, the Kangaroo Point Rock is over 150 years (c1826 to 1976). They had played a significant role in the development the Brisbane City, the Capital city of Queensland, since the 1820s. The kangaroo point rock seen today are not natural as people may think because the rock were created by a volcanic, Meta sedimentary rock. (I.e. metamorphosed rock with sedimentary features such as bedding planes still

Alexander DuToit. Alexander DuToit was a Southern geologist. Alfred Wegener is best known for continental drift. Alfred Wegener was born on November 1, 1880. Alfred Wegener went to Humboldt University of Berlin in 1905. There he studied the way the plates moved. He married Else Koppen Wegener they had one daughter names Elsa Wegener. Alfred Wegener died from congestive heart failure. Congestive heart failure is a weakness of the heart that leads to a buildup of fluid in the lungs and surrounding body

Introduction: My investigation looks into how environmental characteristics change with an increase in altitude along a 750m transect of Dumyat. Dumyat is the frontier hill of the Ochill range, which lies on the north side of the fourth valley, approximately 3.5 miles north east of Stirling. It was formed from the build up of layers of basalt, ash and volcanic mud from the Lower Devonian period, some 410 million years ago. Dumyat is also composed of Andesite, a dark grey igneous rock. The distinctive

Long Island took more than 450 million years to develop into the geography we inhabit present day. Long Island’s geologic history began when future North America (known as Laurentia) collided with continental fragments, resulting in a foundation of consolidated hard rock. Several hundred million years of continental collisions and separations formed the Appalachian Mountains, whose eroding streams delivered Long Island’s sedimentary layer of sand, silt and clay. Over the next 63 million years,

'reverse polarity' describes a situation in which a device, such as a socket outlet, is wrongly wired -with the line and neutral conductors interchanged. The spreading of the sea floor comes from magma oozing up between the cracks between continental plates as lava. This lava subsequently cools rapidly and forms solid rock. The primitive atmosphere was mainly composed of CO2. However, with the emergence of life, this CO2 was reduced in photosynthesis and increased Oxygen. Now our atmosphere is mainly

like surf, overrunning low lying areas. At the shore, tsunamis can be small and undetectable or hundreds of meters high. The Indian Ocean tsunami of 26 Dec 2004 was produced by an earthquake along a subduction zone where the Burma plate overides the Indian plate.

American Plate is moving westwards, where it meets the Caribbean Plate, it is subducted beneath it. This is because the oceanic, South American Plate is slightly more dense than that of the Caribbean Plate. The line of subduction is marked by the deep sea Puerto Rico Trench. As the South American Plate descends, it drags against the Caribbean plate above it. This results in frequent shallow focus earthquakes that get deeper as the ocean plate descends further. As the oceanic plate is subducted

called a Batholith, or Pluton. These are large dome shaped structures made of intrusive igneous rock. Formed when magma cools and crystallizes beneath Earth's surface. They are formed between convergent plate boundaries as one plate subducts under another; leading to partial melting of the denser plate at the Benioff zone. This creates magma less dense than that surrounding it. The magma then cools slowly as it reaches the crust forming large crystals of granite or granodiorite. Surrounding these features
