What is the density of mars compared to earth?

Answer 1

Mars' atmosphere is almost entirely carbon dioxide gas (95%) with only a little nitrogen (3%)(as well as 1.5% argon)

Compare with Earth: 77% nitrogen, 20% oxygen, 1% argon, 1% water vapour, 1% other gases.

Answer 2

Compared to Earth, the atmosphere on Mars barely exists. The average air pressure on thesurface of Mars is about 600 pascals (0.6 kilopascals). That sounds like a big number, but it's actually less than 1% the air density of Earth. So there's very little air pressure.

Furthermore, the composition of the atmosphere on Mars is 95% carbon dioxide, 3% nitrogen, 1.6% argon and then trace amounts of oxygen and water vapor. And carbon dioxide is absolutely something you can't survive on. You need more than trace amounts of oxygen, you need the same levels we have here on Earth to breathe.

Answer 3

Pure water has a density of 1.0. Earth has an overall average density of 5.52, while Mars has an average density of 3.93.

By contrast, iron has a density of 7.87, while gold has a density of 19.32. So we can assume that heavy metals are relatively more scarce on Mars than on the Earth.

Answer 4

mars atmophere is extremely thin and transparent, and is much lighter than earth's. It is thich enough to burn up most small astroids in the innitial entrance.

Answer 5

Mars has an average density of about 3.93 grams per cubic centimeter, while Earth has an average density of about 5.52 grams per cubic centimeter. This means that Mars is less dense than Earth.
