Question

taden has found a table of the atmospheric layers of the sun. however, he can’t make out the names of the layers in the chart.

	a	b	c
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 suns 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:

Match each Sun's atmospheric layer to its position, thickness, and temperature:

1. The Photosphere is the lowest visible layer, ~100 km thick, with a temperature of ~5,500 K, matching column A.
2. The Chromosphere is the middle layer, ~2000 km thick, with temperatures ranging 6,000 to 20,000 K, matching column B.
3. The Corona is the outermost layer, extending millions of km, with temperatures reaching 2,000,000 K, matching column C.

Answer:

A: Photosphere; B: Chromosphere; C: Corona
