What inner planets have atmospheres?
3 Venus,Earth,and Mars (Mercury doesn't have much of an atmosphere there is to less gravity)
What do mars and Venus have in common?
One thing is that both have carbon dioxide as about 95% of their atmospheres. However Mars has a very thin atmosphere and Venus has a very thick atmosphere
Does mercury have a thin atmosphere?
No, the atmosphere is very thin. "Mercury has a very thin atmosphere consisting of surface atoms blasted off its surface by the Solar wind. Because Mercury is so hot, however, these atoms quickly escape into space. Thus, in contrast to the Earth and Venus whose atmospheres are stable, Mercury's atmosphere is constantly being replenished."
Does venus have a big atmosphere?
Venus have a atmosphere. the atmosphere is made of thick cloud of SO2 and SO3.
Why is venus is hotter than mercury even thow mercury is nearest to the sun?
Because mercury doesn't have and atmosphere it isn't able to hold on to the heat from the Sun. So at night Mercury gets VERY cold. Venus has a very thick atmosphere and it is able to hold on to its heat.Mercury:all the heat escapes because it doesn't have a thick atmosphereVenus:has a thick atmosphere and it is able to hold no to the heat unlike mercury
Which 2 inner planets have thick atmospheres?

Which planets have a thick atmosphere?
Define thick - all 4 outer planets plus Venus have thicker atmospheres than Earth.
Which planets have atmospheres?
All the planets in our Solar System have atmospheres, except for Mercury, which only has minute traces of gases.
Why does Venus have higher surface temperature than mercury even though Venus is farther from the sun?
Thick atmosphere on Venus none on Mercury

Which of the inner planets does NOT show evidence of volcanic activity?
none. Mars Earth and Venus have relatively thick atmospheres. it was long assumed that Mercury did not have an atmosphere but a very thin atmosphere around the planet. Mercury's atmosphere is composed of: 42%O2 29%Na 22%H2 06%He 00.5%K
Which rocky planet has only thin atmosphere?
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.
How many planets have atmosphere?
Eight planets in our solar system have atmospheres. These planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
