The atmosphere on Mars is composed mostly of carbon dioxide (about 95.32%), with traces of nitrogen (2.6%) and argon (1.9%). There are also small amounts of oxygen, carbon monoxide, methane, and water vapor.
very thin and made mostly of carbon dioxide.
The atmosphere of Mars is much less dense than that of Earth and is composed almost entirely of carbon dioxide. Earth's atmosphere is mostly nitrogen and oxygen.
The atmosphere on Mars is mostly carbon dioxide.
Mars's atmosphere is composed of about 2.7% nitrogen.
Mars is red because its top layer is composed of mostly iron oxide (rust). The atmosphere appears red because the wind picks up the red dust and carries it.
Mars and Venus are both planets that have atmospheres composed mostly of carbon dioxide.
Mars has a very thin atmosphere composed primarily of carbon dioxide.
