How much air mass needed to raise Mars' atmosphere to Earth's atmospheric pressure?
It would need around 4x1018 kg of air to raise Mars' atmosphere to earth's atmospheric pressure. The answer is formulated under general pressure-depth relation assuming ratio of atmosphere depth is very small to the planet's diameter. P = m.g/A P = pressure = 101300 Pascal at earth's sea level m = mass of air [=] kg g = Mars gravity = 3.7 m/s2 A = surface area of Mars [=] m2
What is an important effect of Mars' low air pressure?
The low air pressure on Mars makes it difficult for liquid water to exist on the surface, which is essential for sustaining life as we know it. Additionally, the low air pressure and lack of a protective atmosphere mean that Mars is more exposed to harmful radiation from space compared to Earth.
How does the air pressure at the surface of the earth compare to the air pressure at about 7 miles above earth?
The air pressure at the surface of the Earth is much higher (roughly 14.7 pounds per square inch) compared to the air pressure at 7 miles above Earth, which is much lower due to the thinner atmosphere at higher altitudes. The pressure decreases with increasing altitude, following the barometric formula.
What inner planet27s atmosphere has low air pressure and it27s mostly carbon dioxide?
Mars has a thin atmosphere with low air pressure that is composed mostly of carbon dioxide. Its atmosphere is about 95% carbon dioxide, with very little oxygen compared to Earth.
Why air is thin on mars?
Mars has thin air because it has a much lower atmospheric pressure compared to Earth, which makes the air less dense. This is due to Mars having a thinner atmosphere and a weaker gravitational pull, causing gases to be less tightly held around the planet.
