X When I was young and saw the picture like the figure1, I think it was not real. It cannot happen in the earth. Maybe someone did Photoshop to edit and retouch the colorful colors in that picture. However, it is a natural phenomenon that happened in the earth 's atmosphere. Galileo Galilei named this phenomenon as "Aurora Borealis." I have three areas of information about auroras to advise you: what aurora borealis is, where the aurora borealis typically seen is, and comparison and contrast this information with Witch Child. The auroras are the colorful shimmering lights movement on a sky that caused by collisions between electrically charged particles released by the solar wind from the sun and gaseous particles in the earth 's magnetic field and atmosphere. You can see the lights above the magnetic poles of the northern and southern. "Aurora borealis" or "Northern Lights" occur around the northern magnetic pole. On the other hand, auroras that occur around the southern magnetic pole are called "Aurora australis" or "Southern Lights." "Aurora," this word comes from the Roman goddess of dawn. It means you can come to see this phenomenon in the earth at the North Pole and the South Pole. Auroras have many colors, shapes, and sizes depending on the solar wind and the geomagnetic field. Type of gaseous particles (atoms of oxygen and nitrogen) and the altitude of the colliding are making many different colors of auroras at altitudes from 20 to 200 miles above the earth 's surface. The common colors and the brightest are glittering green-yellow which produced by oxygen atoms located 60 miles (100 kilometers) above the earth. Conversely, all-red auroras are rare to see and produced by high-altitude oxygen atoms at 200 miles (320 ki... ... middle of paper ... ...at are a physic phenomenon called aurora borealis. Aurora borealis occurs from relationship between charged particles released from the sun and gas particles in the earth 's atmosphere, it is not the lights from God like many peoples on the ship thought (from page 57-58.) In summary, auroras are seen above the magnetic poles of the northern and southern hemisphere. It occurs from collisions between charged particles released from the sun and gas particles in the earth 's atmosphere. I think peoples on the ship in Witch Child saw aurora borealis from a place that closes to the northern hemisphere may be at Greenland. However, they had one idea that different from scientists ' result is the cause of aurora borealis. Many of them believed the lights came from God accept Jonah and maybe Mary. I hope I will go to see aurora borealis, the beautiful phenomenon, in one day.
