Question

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

To determine the Sun's atmospheric layers, we analyze the given data (position, thickness, temperature) and match with known layer properties:

• Photosphere: Lowest layer, ~100 km thick, temp ~5,500 K (matches Column A).
• Chromosphere: Middle layer, ~2,000 km thick, temp 6,000–20,000 K (matches Column B).
• Corona: Outermost layer, millions of km thick, temp ~2,000,000 K (matches Column C).

Other options misalign: e.g., Corona is outermost (not lowest), Core is internal (not atmospheric), etc.

Answer:

D. A: Photosphere; B: Chromosphere; C: Corona
