hi - a slightly more in-depth answer than JRA`s
on easrth - the particles encounter both air resistance [ from still air ] and are affected by air currents [ however imperceptible ]
very fine particles have terrible aerodynamic properties - this is due to thier ratio of mass to surface area
simply put - they do not have the energy to fly a true parobolic arc - as they should if there was no atmosphere - also ANY air current will alter
thier path
also very fine dusts "refuse " to settle and appear to ` hang ` in the air - almost dancing on unseen eddies in the air
but on the moon particles ALWAYS describe a perfect parobolic arc - look at the video of the lunar rover in motion for the finest examples
they WOULD NOT do this in an atmosphere with air currents .
lastly , ask a hoax beliver why there is no evidence of "wind blown dust " independant of the astronauts activity ?
NOTHING in any of the clips / stills moves unless directly affected by an astronaut or thier equipment
hope this helps
