What else can I help you with?
Compare the atmospheres of the four inner planets?
Mercury has a thin atmosphere mostly made of oxygen, sodium, hydrogen, helium, and potassium. Venus has a thick atmosphere of carbon dioxide with clouds of sulfuric acid. Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Do all inner planets have a thin atmospheric shell?
