What are spicules?
Spicules are the eruptions occurring on the Sun’s surface due to the regular upwelling of super granules. Spicules are analogous to the eruptions on the surface of the water boiling in a vessel. Spicules rise up to about 10,000 km above the Sun’s surface.
What are prominences?
Prominences are gigantic geysers of gas which surge out of the Sun. Prominences may fall back into the Sun (sometimes in graceful loops) or they may be thrown out of the Sun and get dissipated. Prominences are analogous to the flames in a fire and can rise more than 1, 00,000 km above the Sun’s surface.
