Transcript: NORTHERN LIGHTS Seen all around the world Gorgeous The solar wind can cause interfenrence with radio, television, and satelite communications. Seen clearly in Alaska and the Northern Hemisphere Lights thought to be gods or goddesses or spirits and souls Troms and Finmark can see it every night. extraordinary too large to measure, abundance of colors, and soooooo prettty! Tour companies offer expeditions to see the Northern Lights. People have reported that the Northern Lights make a sound when occuring. nature's love Other places see it September through April (: First seen 4 1/2 billion years ago In Alska the Northern Lights occur 30 to 40 percent of the nights. Aurora Borealis is named after the roman goddess of dawn. Colors include red, blue, violet, and green Red is the dominant color. Occurs in Scandinavia, Canada, Northern America, Norhtern Europe, and Siberia. Only seen at one time during the year in Europe Occur between 35 and 600 miles above the Earth.

It collides with Earth's magnetic field. In some areas, such as Alaska and Greenland, these lights can be seen on most nights of the year. So lets begin our journey on how the Northern Lights are created. The Northern Lights, one of several astronomical phenomena called polar lights, are shafts or curtains of colored light visible on occasion in the night sky. As the mass coronal energy hits the earths magnetic field it travels to the North and South Poles. As the coronal mass ejection collides with Earth's magnetic field, the energy disperses to the North and South Poles. Colors and patterns are from the types of ions and atoms being energized as they collide with the Earth's magnetic field. The displays may take many forms, including rippling curtains, pulsating globs, traveling pulses, or steady glows. Also, the altitude affects the color of the aurora. When a coronal mass ejection collides with the Earth's magnetic field, it causes complex changes to happen to the magnetic tail region. The start of an aurora starts when a solar storm is created from the suns core. The energy from its core becomes so powerful and emits a solar storm that travels through space. The changes generate currents of charged particles, which flow along lines of magnetic force into Polar Regions. The particles boost with energy and when they collide with oxygen and nitrogen atoms, they produce dazzling auroral light. In a coronal mass ejection, it's speeds can range from, 200 kilometers per second to over 2000. Northern Lights
Transcript: northern lights They are only found in the northern and southern hemisphere. The origin begins at the surface of the sun when solar activity ejects a cloud of gas. Scientist call this Coronal Mass Ejection (CME). if one of these reaches the earth, taking about 2 or 3 days it hits the earth’s magnetic field This field is invisible if you could see it the earth would look like a comet with a long magnetic tail stretching a million miles behind the earth on the opposite direction of the sun. These particles are boosted by the energy in the earth’s upper atmosphere it is from the activity from the ionosphere the changes creates currents of charged particles auroras occurs most frequently during the most intense phase of the 2 year sunspot cycle Did you know Altitude affects the colors…amazing! Some people say they hear noise when they see with the northern lights it’s real name is aurora borealis in the north and is called aurora australis in the south When the coronal mass ejection hits with the magnetic field it causes weird changes to happen to the magnetic tale area The Inuit tell Legends about northern lights. Some Inuit call the aurora aqsarniit say the spirits of the dead are playing football with the head of a walrus. Often they say that the lights will come down and take the children. the earliest observers are from Babylon aroras occuar most frequently diringthe mostintense phase of the 2 year sunspot cycle increases in number. it also makes sharp radiation in the magnetic feild. nolrthern lights are made out of solar particals it also causes magnetic storms you often see three green lines Which then flow along the lines? When the coronal mass ejection hits with the magnetic field it causes weird changes to happen to the magnetic tale area if one of these reaches the earth, taking about 2 or 3 days it hits the earth’s magnetic field northern lights
Transcript: The Northern Lights or Aurora Borealis is one of the most amazing ongoing occurrences in science. They occur in the Artic and Antartic regions. An aurora is caused by the converging of energetic charged particles with atoms in the thermosphere. Auroras ionized or excited. This determination is dependent on the colliding of magnetospheric particles and the solar winds along the earth’s magnetic field lines. When they are exited they are released as oxygen emissions. The emissions are what produce the colors of brownish-red or green. When the ionized nitrogen emissions are released, they create the colors of blue and red. The End! Northern Lights The name Aurora, in aurora Borealis, is named after the roman goddesses of dawn. The Borealis, in aurora Borealis, comes from the Greek name for the north winds which is called boreas. The most recent spectacular ones were seen on both August 28 and September 2, 1859 The magnetosphere and solar wind is where these charged particles are created. These magnificent occurrences are in a band called auroral zone. This zone is usually is in the 3 to 6 longitude.
Transcript: Northern lights aasma: There is a lot of information about the northern lights in the cultures of eastern Asia. The northern lights appeared in China more than 2,000 years ago. Chinese people never used any special name for the northern lights. Instead, the heavenly lights were described by using terms like fire and animals, especially the dragon. roha: now we will show you some pichers aasma:NOW WE WILL SHOW YOU 2 VIDEOs ABOUT THE NORTHERN LIGHTS both: THANKYOU FOR WATCHING AND LISTENING by: AASMA AND ROHA both The End roha : It is the the atmosphere that makes the aurora red and blue and the oxygen that causes the red and green colours to appear. Most aurora lights occur between 90 and 130 kilometres (56 and 80 miles) above sea level, but some, go up to several hundred kilometres . The name 'Aurora Borealis' is Latin . aasma: The Northern Lights are particles from the sun that pass through the shield of earth and create light when they mix with atoms such as nitrogen and oxygen gases on entering into the earth's atmosphere. These particles travel 149 million kms or 93 million miles through space towards planet earth being towards the earth north and south polar regions. roha: The nothern lights has amazed people for centuries. Yellowknife is one of the best places in the world to watch the Northern Lights and The Explorer Hotel can be the base to start your adventure. roha: The Aurora Borealis is also called the northern lights because it is only visible in the North sky from the Northern Hemisphere aasma : Did you know that : The aurora has a curtain- shape, and its lower edge is 95 or 110 kilometres (60 or 70 miles), about ten times higher than a jet aircraft flies.
Transcript: But seriously... some much better than PowerPoint Plot focus Convincing, Engrossing Narrative Characters become secondary Episodic So how does Pullman create these complex characters? Why does Pullman decide to challenge the genre with these complex characters? "JK Rowling and Pullman together dominate children's fiction. This is a capricious market, and Pullman's stories are seen as intellectually sounder, the more heavyweight read in a world where children's fiction is read by adults" Lord Asriel "After many pages, one starts to find the style oddly bland and characterless; ultimately it comes to seem, like other things in The Lord of the Rings, anemic, and lacking in fiber" Archetypal characters & Contradictions ...this is because I was granted permission to use Prezi.com by one Miss Renee Meyer: Richard Jenkyns: Northern Lights Challenging a Genre If you think this presentation looks familiar... Archetypes - "a primordial image, character, or pattern of circumstances that recurs throughout literature and thought consistently enough to be considered a universal concept or situation." - Britannica Online Encyclopaedia For example: the Master could be seen as the wise old man, while Lord Asriel as the fatherly figure. In all these archetypes, each is generally seen as good or evil. Pullman depicts behaviour that contradicts the archetypes of his characters, thereby creating depth. TA-DA!!! Our first impression of Asriel is from Lyra's point of view: "The visitor mentioned by the Master, Lord Asriel, was her uncle, a man whom she admired and feared greatly." Contradicts this impression in the final chapter, where Asriel sacrifices Lyra's friend Billy to open the portal to the other worlds. This revelation at the climax, creates a clear contrast with the previously established notions of his character and as a result, has the reader re-examine his true motives.

Transcript: The northern lights The northern lights are very colorful and only appear during the night and over the coldest spots in the world. Thank you for watching! what are the northern lights? The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Norway is located over by Europe where are they located ? what causes the northern lights to come? The northern lights are lights that appear in the sky because of the type of air around that certain place which is called collisions This is a picture of Norway The most common auroral color, a pale yellowish-green, is produced by oxygen molecules the northern lights are located around the north pole and near Norway
