Question

Consider the following statements about the 'Structure of the Sun':
$1$. Corona is the outermost layer of the Sun having no upper limit.
$2$. Corona is visible with naked eyes on days of partial solar eclipse.
$3$. Chromosphere is the layer where temperature increases as we move away from the surface of the Sun.
$4$. A narrow transition zone separates Corona from Chromosphere.
Which of the given statement(s) is/are correct?

• A. $2$ only
• B. $3$ only
• C. $1$ and $4$
• D. $2$ and $4$

Answer 1

The correct option is C $1$ and $4$

Corona is the outermost layer of the Sun. It starts 2,100 km above the surface of the Sun. It extends millions of kilometres into outer space and is most easily seen during a total solar eclipse. Chromosphere is the layer of the Sun between 400-2,100KM from the surface of the Sun. Corona is the layer where temperature increases as we move away from the surface of the Sun. A thin and very irregular layer of the Sun's atmosphere that separates the hot corona from the much cooler chromosphere.
