Venus has a thick atmosphere. Mercury does not have an atmosphere.
No, it has hardly any atmosphere.
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.
It is very thin.
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
Thick atmosphere on Venus none on Mercury
Venus. It is further away to the sun than Mercury, but Mercury has a thin atmosphere. Venus has a very thick, toxic atmosphere that traps all the sun's heat.
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
mercury's atmosphere is thin so sound waves don't travel very well and there is little oxygen.
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.
Although Mercury is the closest planet to the sun, it is only the second hottest planet after Venus. Venus gets hotter as the thick carbon Dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere.
It has a strong greenhouse effect and its atmosphere is so thick it holds in heat in such a way that it is hotter than Mercury, even though Mercury is closer it the sun, because Mercury has no atmosphere. It is also, near the surface, very high in sulfuric acid vapor.
