Question

The tenuous outer atmosphere of the Sun, which lies just above the chromosphere and, at great distances, turns into the solar wind, is the _____.

a) Photosphere
b) Chromosphere
c) Corona
d) Convective zone

Answer 1

The tenuous outer atmosphere of the Sun that transitions into the solar wind is known as the corona.

Step-by-step explanation:

The tenuous outer atmosphere of the Sun, which lies just above the chromosphere and, at great distances, turns into the solar wind, is the corona. The corona is the outermost part of the Sun's atmosphere and is known for its high temperatures reaching a few million Kelvin. During total solar eclipses, the corona becomes visible and is observed as a bright halo around the obscured Sun. Particles from the corona travel through space affecting various astronomical phenomena such as auroras on Earth.
