Question

a solar eclipse occurs when the moon passes between the sun and earth. which feature of the sun can be viewed during a total solar eclipse?
core
corona
sunspot
convection zone

Explanation:

During a total solar eclipse, the bright disk of the Sun is obscured by the Moon. The Sun's corona, its outer - atmosphere, becomes visible as it is much fainter than the Sun's photosphere and can be seen when the main light source of the Sun is blocked. The core is deep inside the Sun and not visible during an eclipse. Sunspots are on the Sun's surface and are usually not the main feature seen during an eclipse. The convection zone is also an internal part of the Sun and not directly observable during an eclipse.

Answer:

B. corona
