There are a lot more. Each element has several possible absorption lines.
In fact the element iron has several hundred lines.
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
some of the light from the corona produces a continuous spectrum that lacks absorption lines. however the type is absorption spectrum
absorption lines! :)
Light coming up from the centre of the Sun goes through the outer layer where it encounters absorbtion by elements in the outer layer, and this gives rise to absorbtion lines in the spectrum.

because they will have the same elements in the atmosphere...
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.

Absorption lines
because all of the different lines of a star's elements appear together i its spectrum, making the pattern different everytime

Astronomers are able to identify chemicals in distant space with the use of spectral analysis. This breaks the light apart into a spectrum and find either emission lines or absorption lines and identifies which elements are present.
The photosphere of the sun doesn't really produce a continuous spectrum; there are discontinuities corresponding to energy levels of various chemical elements, called spectral lines. Notably Helium was discovered in the absorption lines of the solar spectrum and only later discovered on Earth.

read the Earth science book you will find the answer
