Final answer:
A quiescent prominence is stable and less visible, while an active prominence is energetic and more noticeable.
Step-by-step explanation:
A quiescent prominence and an active prominence are two different types of phenomena observed on the Sun's surface. Quiescent prominences are graceful loops of plasma that can remain stable for many hours or even days. On the other hand, active prominences are relatively rare and appear to send matter upward into the corona at high speeds.
The difference between these two types of prominences lies in their behavior and appearance. Quiescent prominences are less visible and more stable compared to active prominences. Active prominences are often larger and more energetic, making them more noticeable than quiescent prominences.
