NORTHERN LIGHTS
Northern lights is a common name for the Aurora 
Borealis in the Northern Hemisphere.
Where can we see the 
northern lights?
The Northern Lights, as the name suggests, are 
especially related  to the  polar  regions. They  occur  
most frequently in a  belt  of radius 2500 km 
centered on the magnetic  north  pole. This so-called 
auroral zone extends over northern Scandinavia, 
Island, the  southern  tip of  Greenland  and continuing 
over northern Canada,  Alaska  and  along  the 
northern coast of  Siberia .
How often can you see the 
Northern Lights?
 In Troms and  Finnmark , we can see the Northern 
Lights every other   clear   night , if not  even  more 
frequently. From southern  Norway , only a few  times  a 
month  while  in central  Europe  hardly more  than  a 
few times a year and they have even been  seen  from 
the Mediterranean but only a few times each  century
To the north of the auroral zone, the Northern Lights 
are a common sight,  although  they don't appear as 
often as in northern Norway. 
What exactly are the Northern 
Lights? 
The Northern Lights occure when large numbers of 
electrically charged  particles   stream  towards the 
Earth along its magnetic  field  and collide with the 
highest  air particles. The air then lights up. The 
resulting colours reflect in gases we  find  up  there
the most usual  yellow -green  colour  is coming from 
oxygen . Red colouring is also due to oxygen with a 
contribution  from nitrogen. The  violet  we often see is 
due to nitrogen, as is most blue  colouring. 
The charged particles originate from the sun, and it 
is the ' weather ' conditions on the sun that decide 
whether or not we will see the aurora. Particles can 
stream out from the sun and some are captured by 
the Earth's magnetic field and find their way into the 
polar regions. 
How high up are the Northern 
Lights?
Most aurorae occur between 90 and 130 
km  above  sea level, but some, particularly 
the ray-like forms,  extend  to several 
hundred  kilometers up. In  comparison , the 
usual altitude for a jet aircraft is around 
10km and the ozone layer  lies  between 20 
and 30km so we have to be  almost  up at 
the  heights of satellites orbits to be at the 
same  height as the aurora

Energy - põhjalik referaat energiast

2 What Fuels Are Made From Crude Oil?...................................................................60 17.3 How Does Oil Impact The Environment?................................................................60 3 ENERGY STORY Once upon a time, in a town not far away, there was an 8th grader who was afraid of the dark. Her name was Jules. She was also afraid of the quiet, and of the cold. So she always left on the lights, the TV, and stereo even when she had her I-Pod earbuds on. She took lots of very long, hot showers. She never walked anywhere, but got rides from her mom in a big SUV. She couldn't be happy unless she was using all the energy she possibly could for all the stuff around her. Her friend, Les, didn't like to use any energy at all. He walked to school, read books instead of watching TV, played the trumpet instead of Guitar Hero, and turned off the lights anytime he left a room.

Topic - Canada

cultural diversity of different nations in Canada. All the communities living in the country are encouraged to remember their origins and hold their own ethnic events and national festivals. Cultural diversity makes Canada even more interesting. In spite of this, in recent years there is a strong movement in French-speaking Quebec to become an independent country. There are many different native people throughout Canada like the Crees, Mohawks, Troquois and Sioux. In the north of the country, the Inuit (Eskimos) now have a self-governing homeland called Nunavut, meaning our land. It is over two million square kilometers and it is inhabited by 17,500 Inuits. The national symbol of Canada is the maple leaf. The national tree is the maple. Canada is also the most tolerant societies in the world because only 13% of Canadians say that they would object their children marrying somebody of a different race, compared with 32% in the USA.

It is the sixth planet in the solar system, and is most famous for its stunning array of rings. It is a very easy planet to pick out in the sky because it is one of the brightest lights in the shy. It also has a very faint greenish color that makes it stand out from the rest of the objects in the sky ("Astronomy for Kids"). Saturn is the second largest planet in the solar system, Jupiter being the only planet that is bigger. It also has at least eighteen moons, more than any other planet in the solar system. There have been three voyages to this extraordinary planet, and one is still in process today. The Pioneer II traveled to Saturn in September of 1979, the Voyager missions
