describing prominences
which statements describe prominences? check all that apply.
prominences are dark, cool areas on the surface of the sun.
prominences are composed of cool, dense gas.
prominences can disturb radio communications on earth.
prominences cycle over an 11 - year period.
prominences are loop shaped.
prominences appear in groups.

Explanation:

Prominences are large, bright, gaseous features extending outward from the Sun's surface. They are made of cool, dense gas and have a loop - like shape. Dark, cool areas on the Sun are sunspots. Solar flares (not prominences) can disturb radio communications. The 11 - year cycle is related to sunspots, not prominences. Prominences do not necessarily appear in groups.

Answer:

• Prominences are composed of cool, dense gas.
• Prominences are loop - shaped.
