Question

What is the main cause of an aurora?Arrange the inner layers of the Sun in order starting with the innermost layer.

Answer 1

Answer:

i.Core:The center of the Sun where all the Sun's energy is produced.

ii.Radiative Zone:Tiles Energy produced by nuclear reactions in the core travels to this zone through radiation. 

iii.Convection Zone:In this zone, hotter gases from the base travel to the top and  cooler gases sink to the bottom due to the temperature difference.

iv.Photosphere:This zone is visible from Earth. Sequence

When charged particles from the sun strike atoms in Earth's atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights. ~Earthsky
