question 10
what is a corona?
a. the moons penumbra during a solar eclipse
b. the point at which the solar eclipse finally ends
c. the suns glowing ring caused by the moon during a solar eclipse
d. the point at which the moon appears to be a dark disk during a solar eclipse

Explanation:

A corona is the sun's outer atmosphere. During a total solar eclipse, when the moon blocks the sun's bright disk, the corona becomes visible as a glowing ring around the sun.

• Option A: The penumbra is part of the moon's shadow (not the corona).
• Option B: The point where the solar eclipse ends is not the corona.
• Option C: Correct. During a solar eclipse, when the moon covers the sun's photosphere, the sun's corona (a glowing ring of plasma) is visible.
• Option D: The moon appearing as a dark disk is due to its position blocking the sun, not the corona.

Answer:

C. the sun’s glowing ring caused by the moon during a solar eclipse
