As the moon covers the solar disk during a solar eclipse, a flash spectrum of the sun's chromosphere can be recorded. This flash spectrum reveals an emission spectrum and provides information on the properties of the chromosphere. As the moon moves from the inner chromosphere to the outer chromosphere, the spectral lines present in the flash spectrum change. What is going on in the chromosphere

that produces the changes in the flash spectrum? I. The temperature of the chromosphere decreases as the distance from the photosphere increases. II. The temperature of the chromosphere increases as the distance from the photosphere increases. III. The density of the chromosphere decreases as the distance from the photosphere increases. IV. The density of the chromosphere increases as the distance from the photosphere increases. a. I & III b. I & IV c. II & III d. II & IV e. I
