How are earth and Mars are alike and different?
earth and mars are like and different because they have a atmosphere and gravity
Which planet doesn't have a gravity to support an atmosphere?
Mercury and Mars are the only planets without an atmosphere, not including dwarf or exoplanets. This isn't necessarily due to a lack of gravity, however, because Mars is larger than Venus, which definitely has an atmosphere, and gravity is linked to mass.
How would a parachute land safely on Mars which has a thin atmosphere?
Because the gravity of Mars is only 37% that of Earth
How is mars compared to earth?
Colder, drier, smaller, less atmosphere, less gravity
How much pull does Mars have?
On Earth, none at all. Even on Mars, the gravity wasn't enough to retain any atmosphere that it may have had.
How did Mars lose its atmosphere?
The planet Mars is slightly smaller than the Earth and therefore has a weaker gravitational field. Gravity is what holds an atmosphere in place. In a weak gravitational field, an atmosphere will gradually leak away into outer space. That's what happened on Mars.
Can the earth have less gravity and still have a air?
Yes. Both Mars and Venus have weaker gravity than Earth does, but still have atmospheres. Mars has a very thin atmosphere which may have been close to the density of Earth's atmosphere in the distant past, despite having less than half the surface gravity. Venus has about 90% the surface gravity that Earth does, but has an atmosphere many times denser than Earth does.
Can the space suit that's used for the moon can that be used for mars to?
probably not. the earths gravity is different then mars's . the so is the atmosphere so the answer is basically no!
What moon or planet doesn't have enough gravity to have an atmosphere?
-- Mercury -- moon of Earth -- moons of Mars -- majority of moons of Jupiter and Saturn Note: While Mars technically has an atmosphere, its density is only around 1% of the density of earth's atmosphere, so Mars is very close to joining the list.
What inner planets have atmospheres?
3 Venus,Earth,and Mars (Mercury doesn't have much of an atmosphere there is to less gravity)
What is the atmosphere of Mars liike?
mars doesnt have an atmosphere ...
What is the gravity at the surface of Mars?
The force of gravity on Mars is equal to 3.7m/s2. Mars's force of gravity is therefore 37.8% that of Earth's.
