Question

taden has found a table of the atmospheric layers of the sun. however, he cant make out the names of the layers in the chart.
position | a | b | c
lowest | middle | outermost
thickness | 100 km | 2000 km | millions of kilometers
temperature | 5,500 | 6,000 to 20,000 | 2,000,000
what are the names of the sun’s layers described in columns a, b, and c?
a: corona; b: photosphere; c: chromosphere
a: core; b: chromosphere; c: photosphere
a: chromosphere; b: corona; c: core
a: photosphere; b: chromosphere; c: corona

Explanation:

• The photosphere is the Sun's lowest atmospheric layer, ~100 km thick with a temperature of ~5,500 K, matching column A.
• The chromosphere is the middle layer, ~2000 km thick with a temperature range of 6,000 to 20,000 K, matching column B.
• The corona is the outermost layer, extending millions of kilometers with a temperature of ~2,000,000 K, matching column C.

Answer:

A: Photosphere; B: Chromosphere; C: Corona
