Mars is thick to earth
Mars is thin
Thin.
It is thin with 95.32% carbon dioxide
the atmosphere of earth is thick
Earth has a thin atmosphere. Saturn has a thick atmosphere.
Mercury has virtually no atmosphere. Mars has an atmosphere that is much thinner than Earth's, but still thick enough for wind to be important in shaping its surface.
Mars, It has a thin atmosphere of carbon dioxide. Earth and Venus have relatively thick atmospheres due to their larger size, while Mercury's mass is not large enough to sustain any stable atmosphere.
The atmosphere of Venus is very thick, and a parachute would have much greater drag for a given size, than on Earth or Mars. So it could be smaller to achieve the same slowing of a space probe's descent. On Mars, a larger parachute would be required, but fortunately Mars, being a smaller planet, has much less gravity than Earth, so the parachute does not have to resist the same acceleration force (which is roughly the same on Venus as on Earth).
Mars does have a thin atmosphere. Compared to the Earth's atmosphere, Mars' atmosphere is 100 times less dense. It is made up of mostly the elements carbon dioxide and nitrogen.
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.
You can't exactly say an axis is thick or thin as an axis is an imaginary line; it is one dimensional with zero thickness.
Because the gravity of Mars is only 37% that of Earth
