Answer

Brief Explanations:

Mars has a thin atmosphere mainly of carbon - dioxide. Mercury has a very tenuous exosphere, not a thick atmosphere. The atmospheres of Mars and Venus are both mainly carbon - dioxide, making their compositions similar. Earth's atmosphere is mainly nitrogen and oxygen, different from Venus's mainly carbon - dioxide atmosphere.
