In polar tundra areas, there are many beautiful and unique things to witness. If you were to walk through our biome, you would see many polar animals such as seals and walruses. There would be many snowy hills and mountains, along with freezing cold streams and other bodies of water. One gorgeous sight to see in polar tundra regions are auroras. Auroras are luminous
bands of light in the atmosphere. They can be found in the northern and southern areas of Earth. How do you think auroras are created?

I think auroras are created from a chemical reactions, or microscopic organisms in the air.
