Answer to Question 1

A continuous spectrum will peak at a certain color, giving us the temperature of the source. But a continuum can be created by any dense hot body, be it solid, liquid, or gas, and we know nothing of its composition. Emission lines reveal the component atoms in the thin hot gas, and Doppler shifts the motion of the gas atoms. Likewise the absorption lines reveal composition and motion, but that the gas must be too cool to emit the bright line spectrum.

Answer to Question 2

dust
