Prominence
Prominence explained in an easy to understand way:
Imagine trying to keep a pot of boiling spaghetti from overflowing on your stovetop. Just as the bubbling water and noodles rise and sometimes spill over the edge of the pot, the Sun experiences similar eruptions where loops of plasma extend outward. These solar prominences are like those bubbling noodles, both driven by heat and energy trying to escape their boundaries. So, just as you manage the boiling pot to prevent a mess, the Sun's magnetic forces contain these plasma loops, though sometimes they arch far into space before falling back.
Practice Version
Prominence: A huge reddish loop of plasma that protrudes from the Suns surface. Prominence. In simple terms, a prominence is a large, bright feature extending outward from the Suns surface, usually in a loop shape, made of hot gases.
