Carbon Balance in Warming and Drying Tundra 2012

Hi Mr. Wood, I have a question.

  Are there were any other colors besides green, red, and blue for the northern lights, or are they just the main colors?

Hope that you could find a good place to watch them!

See ya soon! -Josh T., period 4

There can be other colors, but those are the main ones. It depends on what type of atom is being hit with the sun's energy. Oxygen gives off green light because there is more of it a high altitudes. They are great!Thanks,
Mr. Wood

Hi Mr. Wood,
I bet they were great and I'm guessing that digging in the snow is very hard! What a tiring day for you!
See ya soon,
