Choose two features of the sun and describe them.

Okay, I am going to use solar prominence and solar flares.

So, Solar Prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominence are anchored to the Sun's surface in the photo-sphere, and extend outwards into the Sun's corona.

A solar flare is a sudden flash of brightness observed near the Sun's surface. It involves a very broad spectrum of emissions, requiring an energy release of up to 6 × 10²⁵ joules of energy (roughly the equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more energy than released from the impact of Comet Shoemaker–Levy 9 with Jupiter).

Hope this helps
