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.
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.
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.
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.

The surface gravity on Mars is about 37% or 3/8 that on Earth.
it is mars it has water
The gravity of Earth is 2.6 times that of Mars.Mars's gravity is 38% of Earth's gravity.
it's smaller than the Earth, about the size of Mars
Really small. 3.68x10^37% in scientific notation.
Earth is big. Mars is small.
the earth is polluted and mars isn't :)
Mars can be compared to Earth, because they both have numerous similarities.
Earth is more dense than Mars because of its huge iron core, which is larger than the planet Mars (if you include both the inner and outer core). Earth's average density is about 5.5 g/cm3, compared to 3.9 g/cm3 for Mars.
Mars is only about half the diameter of Earth.
The Earth is more dense than Mars Mars mean density 3.9335 g/cm³ Earth mean density 5.515 g/cm3
The gravity of Earth is 2.6 times that of Mars.
The surface gravity on Mars is about 37% or 3/8 that on Earth.
