In the chromosphere, the movement of energy is described as flames rising and then returning. What are these flames called?

• A. Spicules
• B. Sunspots
• C. Solar flares
• D. Granules

Answer: (A)

Spicules are the flame-like jets of plasma that shoot upward from the chromosphere along magnetic field lines and then fall back down. Their bright, slender spires rise quickly, then return, which matches the description of flames rising and returning. They’re a dynamic way the chromosphere moves energy and matter upward into higher layers of the solar atmosphere, and they’re typically observed in chromospheric lines like H-alpha. These features last a few minutes and move at tens of kilometers per second. The other options refer to different solar phenomena: sunspots are dark magnetic regions on the photosphere; solar flares are sudden, intense energy releases in the corona; granules are convection cells visible on the photosphere.
