...November 29th, 2012 Volcanoes A volcano is a landform that generally is circular in cross-section that is constructed from lava and tephra erupted onto the Earth’s surface, usually the crust. The opening through which the lava and tephra are emitted is called the volcanic vent. Lava is magma that reaches the Earth’s surface. Magma is melted rock at high pressure and temperature. Magma rises because it is initially less dense than the rock surrounding rock. It eventually equals the density of the surrounding rock and becomes a magma chamber. Tephra is pumice or ash that is blown into the air during eruptions. Volcanoes are generally found where tectonic plates converge and diverge; but are usually not created where tectonic plates slide past one another. As a result volcanoes can be found in all sorts of climate locations. There are four primary types of volcanoes which all have varying effects on the environment. This paper will explore these various types of volcanoes and show how they differ, as well as giving examples of eruptions for each of the types discussed. Principle Types of Volcanoes Cinder cones: Cinder cones are built from particles and blobs of congealed lava ejected from a single vent; they are the simplest forms of volcanoes. Gas charged lava is violently blown into the air and breaks up into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most of these types of volcanoes have a bowl shaped...

...this particular science project they are to build a model of volcano. These students each has their prospective jobs within the small group. One student will work on how to make it erupt, one works on making the platform, one works on cutting the chicken wire, and one is cutting up newspaper strips. The desks in the group are all facing each other, and each student is given an instruction sheet for their particular job. They are instructed to help one another when someone gets stuck, and to check off on their papers when they have finished each step. Another activity I chose was the use of learning centers and computer stations. Some examples of my learning centers for this particular day are the video center on volcanoes, the reading center on volcanoes, and the poster center on volcanoes. I have four groups set up for the students to learn from about volcanoes. The video center is off in the corner, and has a 20 minute video for the students to watch. The reading center is towards one outer wall and has a stack of books and magazines for the students to read about volcanoes. Another learning center has various posters of volcanoes that are packed with useful information about volcanoes. Then there is the computer station where the students can research more information on the web about volcanoes. One behavioral expectation of my cooperative learning groups is to keep the voice volume down between students in the small groups, so as not to disturb other working groups...

...Introduction Plate tectonics is the main process that produces volcanoes, at subduction, convergent, and divergent zones. Yet, we see volcanic activity without the plate tectonics. “Hotspots” are found around the world. Many people who hear of the term hotspots, think of volcanoes and then the association of Hawaii, since it is a very common known hotspot. The Glossary of Geology (1987) defines “hotspots” as “a volcanic center, 100 to 200 km across and persistent for at least a few tens of millions of years, that is thought to be the surface expression of a persistent rising plume of hot mantle material. “Hotspots” are not linked with arcs, and may or may not be associated with oceanic ridges.” “hotspots” are formed in the ocean by producing...

...interaction of the rigid lithosphere. Geomorphological hazard – an event causing harm to people or property, caused by Geomorphological processes e.g. plate tectonic movement. Francis Bacon 1620 As far back as 1620, Francis Bacon spotted that the west coast of Africa and the east coast of South America looked as if they would fit together, like pieces of a jigsaw puzzle. Between then and 1912 other people identified further similarities between other continental coastlines. Robert Mallet 1870s Robert Mallet was a nineteenth century scientist who managed to measure the speed at which earthquakes spread. Alfred Wegner 1911 While at Marburg, in the autumn of 1911, Wegener was browsing in the university library when he came across a scientific paper that listed fossils of identical plants and animals found on opposite sides of the Atlantic. Intrigued by this information, Wegener began to look for, and find, more cases of similar organisms separated by great oceans. Orthodox science at the time explained such cases by postulating that land bridges, now sunken, had once connected far-flung continents. But Wegener noticed the close fit between the coastlines of Africa and South America. Might the similarities among organisms be due, not to land bridges, but to the continents having been joined together at one time? As he later wrote: "A conviction of the fundamental soundness of the idea took root in my mind." Such an insight, to be accepted, would require large amounts of supporting evidence...

...Sidoarjo/Lapindo Mud Flow from A Well in East Java, Indonesia May 29, 2006 By: Yulini Arediningsih Abstract This paper overview the occurrence of Sidoarjo mud flow, known as Lusi Mud Volcano, the world fastest growing mud volcano, triggered by gas drilling exploration. Since May 29, 2006, Lusi mud volcano in Porong sub-district, East Java, Indonesia has been spurting voluminous hot mud and gas, with uncertain knowledge when it will cease. The progressing eruption has been causing major impact on human life, social, economic and environment in this highly populated region. Breached regulations including Indonesian regulations, constitutions, and APPEGGA rules of conduct are outlined. There are five critical concerns related to ethical and professional conduct arising from the occurrence of Lusi mud volcano. The concerns include negligence to best practise procedures, particularly drilling in high pressure zone; conflict of interest between public, government and private sector; violence to human right, public safety; and crisis management related to mitigating the impacts on environment, social, economic especially in compensation process to the victims. 1. Introduction Sidoarjo/Lapindo Mud flow, is geologically identified as a mud volcano (Sawolo, et al 2009). It is generally known as Lusi, a short name of Lumpur Sidoarjo. Lumpur means mud in Indonesian language. Lusi mud volcano is located in Porong sub district, Sidoarjo Regency, East Java Province...

...global warming is due to human actions say that humans are releasing large numbers of heat trapping greenhouse gases into the atmosphere. A few examples of greenhouse gases are “carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and ozone in the lower atmosphere.” (U.S. Global Change Research Information 2006, para. 1). These types of gases get trap heat in the atmosphere and cause the climate to rise. Since the Industrial Revolution, there has been more and more fossil fuels being burned, which is causing more pollutants. The pollutants are trapping heat in the atmosphere causing the average temperature of the Earth to rise. (Turk and Bensel, 2011) The most common heat trapping gas is carbon dioxide (CO2) which is caused by burning fossil fuel, coal, and oil. (Turk & Bensel, 2011) Carbon dioxide (CO2) is produced by so much equipment that humans use and do. Carbon dioxide is produced from burning fossil fuel, coal, oil, driving vehicles, heating systems, cooling systems, logging and even ranching. “The use of fossil fuel currently accounts for eighty to eighty-five percent of carbon dioxide (CO2) being added into the atmosphere.” (U.S. Global Change Research Information, 2006, para. 3). Just by looking at the number of vehicles out there, it is easy to see how much carbon...

...Shake and Erupt: A critical reflection on teaching earthquakes and volcanoes to KS3 Rationale: Perhaps the most dynamic features of the Earth’s awesome power and nature are when Volcanoes and Earthquakes occur. Their workings are at the very core of our planet’s history and their unpredictable activity continues to shake mankind’s understanding of the planet. This topic or scheme of work for my mixed ability year nine class offers a plethora of attributes that both incorporates sound core Geographic knowledge and divers teaching formats that can present a degree of awe and wonder into the minds of young people. Planning and teaching such a topic at a time when the Geography National Curriculum is being reviewed by the new coalition Government, seems to provide somewhat of a blank canvass as to what pedagogical approaches might be the most appropriate to adopt. Whatever the NC will look like, we are led to believe that there will be a re-focus on the ‘core’ knowledge in subjects like Geography. This is not to say a return to didactic teaching where teachers are merely transmitters of information, or indeed to adopt a textbook pedagogy which is reminiscent of the late 1970s and 1980s. The Geography Curriculum Consultation Full Report makes it clear “That a line-by-line, detailed list of geography’s contents is not the best way to draw a positive response from teachers . . . though there is strong support for the national curriculum achieving greater clarity over the core...

...Outline Samantha Hernandez SCI207: Dependence of Man on the Environment Instructor: Alyssa Kunz April 24, 2012 Global Warming 1 Global Warming 2 Is global warming skepticism just smoke and mirrors? There are several different views on the issues of global warming. Some people think global warming might be just a myth while others think that global warming is happening and humans are the cause of it. One side believes that humans cause global warming, yet the other side thinks that global warming is a complete fallacy. I. Global warming is an environmental issue that is concerning a lot of people. Global warming has been an issue for many years. One area of this issue that is taking over right now is whether global warming is due to human actions or if global warming is due to natural cause there is a big argument over it. Some people believe global warming is due to human actions of pollutants such as burning fossil fuel, coal, and oil, human finger prints, and deforestation; while other people believe it is a natural cause and global warming is just a theory and nothing else. A. According to some people and scientists there is a huge impact of this environmental issue on the world and something needs to be done right now in order to try and stop or slow down global warming. On the other hand, some people and scientists believe that humans do not cause global warming; instead it is a part of history and would occur with or without the help...

The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation. DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer...

...The Continuing Process of Parental Grief Also, sometimes a parent's love makes them unable to let go. I've seen so many parents put their needs above their infant's because they just can't bear to suffer the grief of losing a child. It's heartbreaking when you can see parents in total denial and you know that the end will come one way or another but they just can't accept it. I don't know if that's the case here or not, but it's certainly a possibility. Parental Grief The theme of parental mourning has been a universal one throughout the centuries. In the literature on bereavement, writers repeat certain themes, thoughts, and reflections; they talk of the powerful and often conflicting emotions involved in "the pain of grief and the spiral of mourning; [they refer to] the heartbreak at the heart of things...grief's contradictions"; they speak of parents devastated by grief (Moffat 1992, xxiii). It is frequently said that the grief of bereaved parents is the most intense grief known. When a child dies, parents feel that a part of them has died, that a vital and core part of them has been ripped away. Bereaved parents indeed do feel that the death of their child is "the ultimate deprivation" (Arnold and Gemma 1994, 40). The grief caused by their child's death is not only painful but profoundly disorienting-children are not supposed to die. These parents are forced to confront an extremely painful and stressful paradox; they are faced with a situation in which they must deal...
