Why do northern lights appear in different colors? because charged particles of solar wind ignite different gases in earth's atmosphere because electrons and protons of solar wind ignite the plasma present in the corona because electrons and protons of solar wind cause severe proton showers on earth because charged particles of solar wind cause solar flares on the surface of the sun

It is A. Because charged particles of solar wind ignite different gases in Earth's atmosphere.

Explanation:

Since the solar wind from the sun is too radioactive for humans (they would die), once the charged particles hit the earth's atmosphere it shows its color. Every element has its own color and once it hits the atmosphere it really starts to show.

there is none because earth is stationary and flat.
