Mars has a very thin atmosphere that is made mostly of carbon dioxide.
- 95.72% CO2
- 2.7% nitrogen
- 1.6% argon
- 0.2% oxygen
- 0.07% carbon monoxide
- 0.03% water vapour
- 0.01% nitric oxide
- and trace amounts of neon, krypton, formaldehyde, xenon, ozone, and methane.
Its atmospheric pressure is 7-9 millibars, depending on the season. This is only about 1/100th as dense as Earth's at sea level (1013.25 millibars).
The average temperature is about -80 degrees C.
During winter some of the atmosphere freezes into dry ice at the poles.

What are the similarities between Venus and mars?
Mars and Venus both have a core which made of metal and they belong to the inferior planets of our solar system.They are also rocky planet like our earth.
What are similarities between mars and Saturn?
Very few similarities exist between Mars and Saturn. Mars is a smallish terrestrial (or rocky) planet, while Saturn is a large gas giant planet. Mars has two small satellites, while Saturn has dozens of large satellites, and millions of small ones that form the "rings" of Saturn.
What are similarities between Earth and Uranus?
The similarities of Earth and Uranus are that they both: are round. have gravitational pull. have an atmosphere that creates a blue tint. have moons. are planets. circle the sun as part of the solar system. spin on their axis, even though Uranus' axis is tilted way over. have solid parts, liquid parts and gaseous parts.

Which two inner planets have atmospheres that consist of mostly carbon dioxide?
Venus and Mars. The difference is that Venus atmospheric pressure is around 93 times that of Earths, while Mars' atmospheric pressure is only 0.7% of Earths.
Similarities between Mars northern and southern hemisphere?
There are no significant differences.
Do earth and Mars have different atmospheres?
Yes
Which terrestrail planets have atmospheres?
Venus, Earth and Mars.
What are similarities between mars and Saturn?

Is Earth and Mars the same planet?
No, Earth and Mars are not the same planet. They are two separate planets in our solar system with distinct characteristics, such as different sizes, atmospheres, and surface conditions. Mars is known as the "Red Planet" due to its reddish appearance, while Earth is the only planet known to support life.
What are the similarities between mars and moon?
Mars and the Moon share several similarities, including their rocky terrain and the presence of impact craters, which indicate a history of collisions with celestial bodies. Both lack significant atmospheres, leading to extreme temperature fluctuations and limited weather phenomena. Additionally, they both have polar ice caps, with Mars having water ice, while the Moon has frozen water in shadowed craters. Their exploration has provided valuable insights into planetary geology and the potential for past water presence.
Could you list the planets in order from the thickest to thinest atmospheres?
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.
What is similar about mars and earths atmosphere?
Mars and Earth both have atmospheres that contain carbon dioxide, though in vastly different proportions. While Earth's atmosphere is composed of about 78% nitrogen and 21% oxygen, Mars has a thin atmosphere made up of about 95% carbon dioxide, with only trace amounts of oxygen. Both planets experience weather phenomena, but Mars has much lower atmospheric pressure and a colder climate. Additionally, both atmospheres have been studied to understand potential for past life and future colonization.
How are the atmospheres of earth and mars alike?
Both Earth and Mars have atmospheres composed primarily of carbon dioxide. They both experience weather patterns and have polar ice caps. However, Earth's atmosphere is significantly thicker and has more oxygen than Mars.
What are Mars' moons' atmosphere like?
Mars has two moons, Phobos and Deimos, both of which are small and have very thin atmospheres. Their atmospheres consist mostly of carbon dioxide, with trace amounts of other gases such as nitrogen and oxygen. These atmospheres are so tenuous that they do not offer any significant protection or support for any form of life.
