What Causes Earthquakes

It takes an earthquake to remind us that we walk on the crust of an unfinished planet. “Charles Kuralt” Earthquakes as the name implies are among the earth’s natural disasters. Earthquakes are mother nature. Earthquakes are the trembling or shaking caused by sudden release of energy which usually associated with faulting or breaking on rocks. The tectonic plates are always moving. The moving causes the earthquakes and the earthquakes causes disasters. According to my research, l discovered that there are four types of earthquakes and their causes. First, the explosion earthquakes are man-made earthquakes and occur due to nuclear or chemical explosions. Collapse earthquakes are minor earthquakes that are caused by the collapse of undermined areas like caves and mines. Also, the sudden eruption of volcanoes can cause earthquakes. These occur when lava under the earth’s crust is under pressure and as a result of the pressure the lava is thrown out causing earthquakes. Furthermore, the most common causes of earthquakes are the tectonic plates. These plates are always moving, but they get stuck at their edges due to friction. When these plates move, they grind against each other. The motion of these tectonic plates is what causes earthquakes. Examples would be the earthquakes that happened in Haiti in 2010 and in Japan in 2011. The consequences of earthquakes are many. Earthquakes destroy buildings, roads and other structures. People died or become injured as a result of earthquakes. Houses are destroyed causing homelessness to the survivors. Transportation and communications may be disrupted. Earthquake causes fire that can spread due to gas-pipe explosions. Fire can destroy farmland thereby causing food shortage. In conclusion, earthquakes are most…...

What Causes Truancy?

...What Causes Truancy?   The reason a student misses school will for different depending on the age and circumstances of each student. Sometimes a student will skip school because they feel unsafe at school or on their way to or from school. Other students may miss school because of family issues, financial demands, substance abuse, or mental health problems. Factors contributing to truancy commonly stem from three core areas: school, family and community. Innate student characteristics and their experiences within all these areas will have a heavy impact on truancy rates.  Bad Influences One of the common causes of truancy and disruptive behavior in children is the influence of friends and peers. Many times these peers are seen encouraging truancy as a status-seeking activity or as a way of joining in or blending in. The child's natural instinct to want to be a part of a larger crowd or group dynamic will take over, even if they are taught better habits. Often times this same dynamic is prevalent in the face of any resistance the child may put forth, prompting teasing or goading the child into truanting. School What is classed as truancy can depend largely on the school's attitude to the 'truant' or their problems. Relationships with teachers, seen as lacking respect/fairness, play a large factor in truancy rates among children. Often times this inability to get along with teachers and/or students will result in disciplinary problems which may lead to suspension, or......

What Cause Students Stress

...What Cause Students Stress Over 30 percent of college students report feeling overwhelmed at the demands of university life, according to the University of California-Los Angeles. That stress isn't limited to college students. Students of all ages, in fact, can feel anxious about life and the future. Stress affects not only the mind, but also the nervous and immune systems, making it harder to fight off illnesses and infections and more difficult to sleep. Grades One of the biggest contributors to students' stress is the need to perform well in the classroom in order to get high grades. For high school students, grades can affect college placement, scholarships and even privileges at home. In college, grades play an important role in scholarships, the ability to play on sports teams and moving on to higher levels of education. Peer Pressure Whether it's the temptation to do drugs, drink alcohol, go to parties or even cheat, students can sometimes feel bombarded with pressure from their peers to do things that are either harmful or distracting. Trying to please friends while fulfilling other obligations can contribute to the stress. Hard Decisions As students advance in high school and college, they are faced with some of the biggest decisions in their lives. Choosing a college and a major and deciding what to do after graduation can cause stress. Students may be fearful of making the wrong decision or dealing with outside influences, such as parents or friends who are......

Multidimensional definitions acknowledge that poverty is also defined by a sense of helplessness, dependence and lack of opportunities, self-confidence and self-respect on the part of the poor.

What Cause Humans to Become Ill

...What causes humans to become ill? Humans can get ill a variety of different ways, anything we eat or come into contact with may cause illness in a human. In this essay I will outline different potential illnesses that a human may suffer with. When a human comes into contact with something that causes an abnormal immune response we call it an allergy. When allergy-prone person initially comes into contact with an allergen their B-cells produce IgE antibody, this antibody produced binds to mast cells which are found throughout the body. The second contact with this allergen, the mast cells with IgE present produces histamine which then lead to allergy symptoms such as running nose, sneezing and watery eyes. There are millions of types of different bacteria, some good and some bad called pathogens, which can make a human ill. When a pathogen enters the body it attaches to cells, potentially damaging the cells and releases its toxins. The bodies white blood cells can destroy the pathogens however while the body destroys the pathogens it may also damage the surrounding tissue. In most cases antibiotics can be taken to kill the bacteria, it does this by stopping their growth or killing them it does this by preventing the bacteria from building up a cell wall. An example of a bacteria is acne, acne is caused by bacteria growing near or in the sebaceous glands in the skin which causes inflammation and white pus.

What Causes People to Get Tattoos

...“What causes people to get tattoos?” Tonny Cobos SOC100030VA016-1146-011 August 18, 2014 What causes people to get tattoos? Who doesn’t have a tattoo or know someone who does in modern society? 16% of all adults in the United States have at least one tattoo (Harvard Health).  In today's society tattoos are completely acceptable. America is the melting pot of the world where diversity and cultures are welcomed. Society is begging to accept “ink”. People that work in business usually have them where they are not easily seen, but a roofer for example it is okay to have them where they are easily seen. If a tattoo is placed appropriately on your body and it is something tasteful, why not. Many celebrities state “tattoos aren't there just to look cool and different. Tattoos have special meaning and they are real, permanent tattoos” (Johnson). This is in no way supposed to stereotype anyone, but to answer some questions about why a person would decide to get something permanently imprinted on their skin.” First there is the reason of a loved one (Jackson).Then there are religious tattoos, many people get this tattoo as a sign of devotion to their beliefs, and is very commendable (Jackson). Next there is the military tattoo Jackson (2007).Then there is the just for fun tattoo. Finally there is the “oh no” mistake tattoo. Of course there will be tattoos that do not fit into any of these categories, but these are definitely common reasons. Tattoos remind people of their......

What Causes Crime?

...What Causes Crime? Crime has existed in societies across the world since the term crime has been implemented. The standard definition of crime, if one can use the term standard, is any action that is prohibited, prosecuted, and punished by criminal law. Therefore, crime cannot exist without some form of legal system to label criminal behavior. The mandatory existence of a legal system for criminal behavior to occur can be easily confused with actions that violate socially constructed norms, or deviant behaviors. It is with that premise that I propose crime is caused by a conflict of interest. This conflict of interest is not limited to the interactions between classes, groups, or individuals; the conflict of interest is intentionally vague so as to not cause further damage to criminological understanding by imposing misleading specificities. Crime is a conflict of interest between two or more variables, with at least one variable involving one or more humans. I propose crime is a conflict of interest because the term interest can encompass the two key aspects of profit and loss that is the rational basis for creating legal systems. However, as so many have noted, illegality is at the end of the day typically decided by those who create the laws rather than those most affected by the laws. Conflicts occur when there lacks a unanimous consensus among all parties considered in a given situation. When countries consist of millions of people, one can note how even the......

What Is Earthquake?

...What is EARTHQUAKE ? An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that createsseismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe. The more numerous earthquakes smaller than magnitude 5 reported by national seismological observatories are measured mostly on the local magnitude scale, also referred to as the Richter scale. These two scales are numerically similar over their range of validity. Magnitude 3 or lower earthquakes are mostly almost imperceptible or weak and magnitude 7 and over potentially cause serious damage over larger areas, depending on their depth. The largest earthquakes in historic times have been of magnitude slightly over 9, although there is no limit to the possible magnitude. The most recent large earthquake of magnitude 9.0 or larger was a 9.0 magnitude earthquake in Japan in 2011 (as of March 2014), and it was the largest Japanese earthquake since records began. Intensity of shaking is measured on the modified Mercalli scale. The shallower an earthquake, the more damage to structures it causes, all else being equal.[1] At the Earth's surface, earthquakes manifest themselves by......

What Causes High Gas Price

...What Causes High Gas Prices? There are various factors that play a role in the price consumers pay at the pump. The major cause in the fluctuation of gas prices is crude oil. Crude oil is that main ingredient involved in the manufacturing of gas. One body that has great influence over the worldwide price of oil is the Organization of Petroleum Exporting Countries (OPEC). OPEC is made up of twelve of the world’s biggest oil-producing nations which include: Algeria, Angola, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, United Arab Emirates, and Venezuela. Since OPEC’s nations produce so much of the world’s oil supply, they can control the level of production. Oil is one of the world's most important commodities, and as a result, the nations that control the majority of the world's supply have a great deal of power over its availability. In addition, conflicts such as war in an oil-producing region can also bring up the price of gasoline. Andre Gerolymatis, a history professor at Simon Fraser University, says political upheaval in Ukraine and Russia's military incursion into Crimea could be putting pressure on prices. The reason, of course, is that 40 per cent of Europe's gas and oil comes from Russia, and it comes through the Ukraine. So there's the potential that this could be disrupted, and that means that the Europeans would have to go elsewhere for gas, and that would drive the prices up. (Bains, 2014) Bibliography Bains, M.

In my opinion, the causes of people drinking are; being socially pressured: dealing with stress, and because of social circumstances. First, people can be pressured to drink? A person does not always have the desire to drink. We are faced with decisions when we got to restaurant. Businesses use a sales strategies called suggestive sales to impulse you to purchase liquor. This helps generate more cash for businesses. Applebee’s greets you with the suggestions of alcohol. Every day of the week, they have a special or half priced drinks that have been marked down at very low price. This business believes if they offer drinks at a lower priced, this can persuade customers to buy it. Also, people are pressured to drinks by others who drinks such as coworkers, family and friends. These individuals can influence you to drink by inviting you to attend social gathering and parties where alcohol present. The fear of being rejected can pressure you into the consumption of this addictive beverage. Drinking alcohol can be used as a way to deal with stress. Stress from work, kids, family, coping with death. Dealing with a stressful job can cause enough stress for you to drink.

What Is the Main Cause for Violence?

...What is the Main Cause for Violence? January 12, 2014 Victimology What is the Main Cause for Violence? Violence has been around a very long time. The first record of violence is probably the story of Cain and Abel where Cain had become jealous of his brother Abel and murdered him, thus the first act of violence. No one really knows why people choose a violent road to go down and to commit crimes but there are many theories. Some say it is how they grew up in society and the people they hang around or on the other hand people say they are simply wired from birth to be that way. My paper is a reflection of my opinion on what I think the main cause of violence is and whether or not it is biological or social and what can be done to correct it. In my opinion, I think violence stems from both biological and social stand points. Let’s just focus on the social aspect of violence first and the influences around us. Many people and I speak from experience stereotype certain individuals because of the neighborhood they live in, the color of their skin, or the company they keep. Sometimes these stereotypes can be true. For someone to be socially accepted into a group such as a gang, they have to be tuff and basically a criminal. As some kind of initiation they need to commit violence whether it’s shooting someone or robbing a store for example. I believe society puts pressures on young adults especially they have to have a certain way of life and the only way they can fit in......

What Are the Causes of Urban Air Pollution?

...population in developing countries will have more than doubled to 4050 million. Against a prevailing background of rapid urban growth and variable treatment of pollution problems, the future health of the majority of the world’s urban residents is likely to be in jeopardy. Sulphur compounds give the earth’s atmosphere a kind of built-in ther­mostat. They scatter sunlight back into space before it can contribute to global warming. However, the problem is complicated by the action of sulphate aerosols which are distributed unevenly in the world and which have no effects during the night. Eliminating sulphur emissions can be effective in accelerating the warming by greenhouse gases. References: http://www.shareyouressays.com/111965/what-are-the-causes-of-urban-air-pollution...

What Causes People to Migrate Illegally?

Many reasons are behind people who want to migrate to another place such as, a new life, not happy by the way they are living, wanting a better life for their family, etc. They are a big part in peoples lives for wanting a stable life for them, wanting nothing but the best not just for them but for their families also.

When utilizing the world wide web many persons choose to use an avatar instead of presenting their authentic selves. They are often used in online video games and on various sites that require some sort of user representation.
