Question

question 8 of 23
which of the suns layers is visible only during an eclipse?
a. the chromosphere
b. the photosphere
c. the ionosphere
d. the corona

Explanation:

• The chromosphere is a layer of the sun's atmosphere. It is usually hidden by the bright light of the sun's surface (photosphere). But during a solar eclipse, when the moon blocks the photosphere, the chromosphere becomes visible as a thin red - colored layer.
• The photosphere is the visible surface of the sun under normal conditions.
• The ionosphere is not a layer of the sun. It is a region of Earth's upper atmosphere.
• The corona is the outermost layer of the sun's atmosphere. It is visible during a total solar eclipse as a bright halo around the sun.

Answer:

A. The chromosphere
