The Aurora Borealis

Today, I am writing about the aurora borealis. It’s a phenomenon that makes the sky extremely colorful. It can only be seen in the north and south poles because of chemicals that try to enter earth’s atmosphere. They can’t thanks to earth's magnetic field, so they go to the weakest spots (north and south pole). When they enter earth’s atmosphere; they create all sorts of beautiful sunsets. They can turn the sky green, blue, pink or purple. Pictures of the aurora borealis can be seen below. The Vikings believed that the aurora borealis to be a bridge to heaven. Bye!!!!!!!!!!!!
