Is the Aurora Borealis found in the mesosphere?

Answer 1

The Northern lights can be seen round the magnetic North pole of the Earth in the Arctic Circle. High energy particles of the Solar wind are guided to Earth down field lines and excite air molecules to glow. The Aurora Australis occurs over Antarctica

Answer 2

Aurora borealis occur in the Earth's ionosphere, and result from collisions between energetic electrons (sometimes also protons, and even heavier charged particles) and atoms and molecules in the upper atmosphere. The ultimate origin of the energy which powers the aurora borealis is the Sun - via the solar wind - and the Earth's magnetic field. Interactions between the solar wind (which carries its own tangled magnetic fields) and the Earth's magnetic field may cause electrons (and other particles) to be trapped and accelerated; those particles which do not escape 'downstream' to the magnetic tail 'touch down' in the atmosphere, close to the north magnetic pole.

The different colors come from different atoms or ions; green and red from atomic oxygen, nitrogen ions and molecules make some pinkish-reds and blue-violet; purple is the appearance of combined colors from nitrogen ions and helium; neon produces the very rare orange. The ionosphere is home to most aurorae borealis, with 100-300 km being typical (this is where green is usually seen, with red at the top); however, some particularly energetic particles penetrate much deeper into the atmosphere, down to perhaps 80 km or lower (purple often comes from here).

Answer 3

The aurora borealis and aurora australis occur in the Ionosphere from around 100 km up. This layer of the atmosphere is also called the Thermosphere.

Answer 4

Yes, it is because the Aurora Borealis, also known as the northern lights, are in the north pole and well, the north pole is in the troposphere
