Space Weather Essay Example for Free

Space Weather Essay Space weather is what happens in space and how it affects the Earths weather. Even though in space it may not look like a big thing but when those effects reach Earth it can make a huge impact on the Earths weather. It can cause natural disasters such as floods, hurricanes, etc. Space weather doesnt just affect the Earths weather but it can also affect new technology. Its been causing problems with new technology as early as when the telegraph was invented in the 19th century. Solar flares can disrupt power grids, get in the way of high-frequency airline and military communications, disrupt GPS signals, interupt civilian communications, etc. Space weather can cover the Earths atmosphere with a hazardous and dangerous radiation. Even the technology we use like traffic lights, cell phones, street lights, etc could be affected by a solar flare. Furthermore stuff like solar flares have been occuring more often since global warming started to become more gruesome. This is because of the amount of carbon dioxide in the atmosphere along with other gases and these gases are trapped in the Earths atmosphere and the more gases are trapped in the atmosphere the less gases are let out into space. This can create problems like species extinction, flooding around coastal areas, make seasons longer then they should be, more frequent and severe storms, and alter temperature patterns. Along with solar flares, solar winds can also affect the Earhs weather. This is because the intense clouds of high energy particles which are often made by solar storms and make their way to Earth in about 3 to 4 days it collides with the Earths magnetic field. The particles enters Earths magnetic field near both north and south poles. When that happens it causes many problems with technology. Like solar flares and solar winds magnetic storms can also cause damage to our way of life on Earth espically now since we rely on technology so much. Magnetic storms can pump extra electricty into our power lines and pipelines causing blackouts and gas leaks. For example, in March 1989 a magnetic storm caused a thirty-six million transformer in New Jersey collapsed the entire power grid in Quebec, Canada. When that happened it left six million people without electricity. Space weather can also be very hazardous for astronauts. For example, in between the flights for both Apollo 16 and Apollo 17 an intense solar flare occurred. This would have killed the astronauts on board Apollo 16 and Apollo 17 if they had been on their way to go to the moon during that time. These are just some of the many things on how space weather can affect the Earth and the Earths weather. Just to remind you space weather is what happens in space and how it affects the Earth and its weather. It can make a huge impact on Earths weather and Earth even though in space it may not look like a big deal. These are some ways space weather affects the Earth and its weather.

Mortuary Practices and Afterlife of the Choctaw Essays -- Sociology, T

The Choctaws thrived in the fertile sandy, red-clay soil, rolling hills, and dense forests, located in the Central Hills of the east-central region of Mississippi. The estimated population after early European contact was between 15,000 and 20,000 and was the second largest group of Native Americans in the Southeast (Blitz 1988:127). The Choctaws in the Southeast were a matrilineal society. Traditionally, women preformed tasks related to domestic life. Among these responsibilities were creating pottery and utensils, food preparation, and planting and harvesting crops. The majority of their diet consisted of agricultural products such as corn, pumpkins, squash, and beans. Women would also accompany men on hunting excursions in order to provide food preparation. After the hunt, women were responsible for transporting the slain animal back to the village for processing of skins, bone, and meat (Carson 1995:495-6). The greatest responsibilities of the Choctaw men were hunting and warfare. During the fall and winter months, their primary food source was deer. Their accomplishments on hunting adventures directly reflected upon their social status and importance within the tribe (Carson 1995:197). Although the Choctaw shared much of their culture with many of the other tribes in the Southeast, â€Å"in the disposition of their dead, the ancient Choctaws practiced a strange method different from any other Nation of people, perhaps, that ever existed† (Swanton1931:176). When a Choctaw tribal member became terminally ill, it was common practice for the medicine man to inform the family of impending death (Swanton 1931:170). The women cleansed the body, applied paint, daubed the face, and dressed him in his finest clothes. He was the... ...ld winds always blew. Every spirit encountered was an enemy with no safe place to take refuge. Food was scarce, due to unfertile soil, lack of game, and hunger was constant. The bad hunting grounds are perpetually lonely, with only the joyous sounds from the other side of the mountains. The doomed spirits constantly struggled to climb the treacherous mountains, but to no avail. They were eternally destined to an afterlife of desolation (Campbell 1959:149-52). The Choctaws possessed unique ceremonies in regards to their deceased as well as a vivid explanation into their afterlife. Through many accounts, the knowledge and customs of the Southeast tribe of the Choctaw will not be forgotten. Although these customs may not be practiced, the extensive documentation gives an extraordinary glimpse into the lives of the natives of the southeast United States.

Our Home and Racist Land Essay

Being one of the most socially developed and multicultural countries in the world everyone probably sees Canada as a Utopian country. Unfortunately Canada isn’t as perfect as everyone thinks it is, and a major persisting issue is racism. Being a multicultural there are many minorities and this usually results in racism, isolation, and unequal treatment amongst everyone. Unfortunately, racism gets more serious and turns into hate crime and that is a federal offence. Racisms not only affects adults at work or on the streets but also affects children in schools and daycare centers as kids are treated differently based on their skin color. We can all imagine that racism has disappeared but in reality we know that it will never leave. Racism is defined as a belief that inherent differences among human race, does that mean that all of us have to be one race in order to eliminate racism in our society? Practically, it is impossible to get rid of racial prejudice. Racism is common amongst the streets of Canada and especially Toronto as we are the most diverse city in Canada. Racism occurs everywhere from schools to workplaces. Even where I volunteer the guy who runs is racist, he is known for only hiring white people as his staff and Hispanic people to do the cleaning. Everywhere we turn we see racism. When a lady crosses the street and sees a person of African descent she will either take a different road or being to walk really fast. This is because we are all racist by habit now. We have been influenced by movies, TV shows, and the media. We are always bombarded by â€Å"20-year old black male wanted for robbery† or â€Å"32 year-old male black wanted for murder† in the media that everyone has come to a conclusion that all black people are criminals and that is wrong. To make matters worth parents will tell their kids not to hang out with â€Å"African† people and when that one African child gets secluded he will do anything to be part of the â€Å"group† and this is when the child starts to befriend the wrong people and he is now in a gang. He gets into unnecessary trouble and now is the top news on CTV and all of this was because one arent was racist and told his/her child not to be friends with a black person. A more severe case of racism is hate crime, and that is very common in Canada. Statistics Canada has released the numbers and it states that there have been 1473 hate-motivated crimes in 2009 and 52% was because of race/ethnicity, which means there have been 766 racist crimes. To be more specific almost 300 incidents were intended toward black people, 95 towards south Asians, and 75 towards Arabs. Even in the 21st century we are still witnessing violence toward people because of their skin color. Just by viewing these statistics you can conclude that Canada is still racist. To be more precise Canada has increased in hate crimes toward race from 2006-2009 by roughly 61%. Racial discrimination must stop immediately; it is not progressing society forward it is pulling us backward. At the end of the day we are all humans and we are all one race and this prejudice towards others because of the color of their skin is barbaric. Canada is most definitely still racist, we might seem like the perfect country to the eyes of others but we are far from a utopian society. Regardless of the fact you are Caucasian, African, Sri Lankan, Arab, and Chinese we are all humans, and racism just degrades us. Abraham Joshua Herschel, a Polish-born American rabbi once said â€Å"Racism is man’s gravest threat to man – the maximum hatred for a minimum of reason. â€Å" Racism was once the reason WWII had started and it was the reason we went through a terrifying era of slaves in North America. Both Canada and the global society are frequently showing racial animosity and this should not be tolerated.

Chemical Warfare During World War II - 1450 Words

Chemical Warfare in World War 1 Chemical Warfare is defined as â€Å"Tactical warfare using incendiary mixtures, smokes, or irritant, burning or asphyxiating gases†. This is the usage of a chemical to harm the opposing side in order to get an advantage in the war at hand. Three of the main chemical weapons used during World War 1 were Lachrymator (tear), Chlorine and Phosgene, and Mustard gas. Chemical warfare was overall effective in World War 1 because it added to the weaponry needed to win the war. In the start of World War 1 gasses were considered inhumane and uncivilized. These three types of gasses show exactly why that was the thought all around the world on chemical weaponry. Lachrymator (tear gas) - caused temporary blindness and irritation to the victims’ nose and throat. A gas mask would give the troops relatively good protection from this type of gas. Sternutator (poisonous gas) - chlorine, phosgene. Chlorine gas combines with moisture so it attacks the soldiers’ eyes and lungs. Phosgene gas was used along with Chlorine gas; it would cause less coughing allowing more to be inhaled. Also the effects were delayed for a longer time than when Chlorine gas was present. Troops would most likely be affected up to 48 hours after their body was initially introduced to the chemical. These two where later mixed together. The Chlorine helped the vapor to spread wider and faster than Phosgene had before causing both gases to be deadlier then before.
