- js2 6y agoMiriam Webster says yes to part two: > the mixture of invisible odorless tasteless gases (such as nitrogen and oxygen) that surrounds the earth > also : the equivalent mix of gases on another planet I would naively guess yes to part one but it's complicated: Mars has less gravity, much less atmospheric pressure, colder temps, and greater gravitational influence from its moons than Earth. Wikipedia says the mechanism of the planet's dust storms isn't well understood. https://en.wikipedia.org/wiki/Atmosphere_of_Mars#Dust_and_other_dynamic_features https://en.wikipedia.org/wiki/Atmosphere_of_Mars#Dust_and_ot...

- mrec 6y agoRight. One "proof" advanced by Moon landing conspiracy theorists was that dust settled much faster in videos than it should if it were really in Lunar gravity.
- DonHopkins 6y agoYes, but it's not technically correct to call Martian seismic tremors "earthquakes". https://www.imdb.com/title/tt0080745/goofs https://www.imdb.com/title/tt0080745/goofs Flash Gordon (1980) Goofs At the very beginning of the film, Ming and his henchman are discussing "an obscure body in the SK system", which the inhabitants refer to as the planet "Earth", pronounced as if the word is completely foreign to them. However, at that moment, Ming activates a button on his console labeled "Earth Quake". http://bobcanada92.blogspot.com/2020/10/flash-gordon-logic.html http://bobcanada92.blogspot.com/2020/10/flash-gordon-logic.h...
