infinitesimal point. Electrons and other leptons are points, neutrinos are points, photons are points, quarks are points. it has been shown that they all have no measurable size or certain phenomena must occur that have never been detected.
it all builds up
It depends on how strong the wind is, and where and how far reaching that wind is. Also, if there is little vegetation to trap the sediment, more of it will be carried away by the winds. The classic example of this would be the dust bowl in America. This was caused by bad farming methods, which stripped the west of it's native grass. THis allowed Huge dust storms to blight the whole Midwest, and in one case, carried dust and sand from the far west all the way to the Atlantic ocean! So basically, size of particles, wind speed and opportunity for erosion all play into how dust is carried in the winds
There are actually three processes that move sediment, all involving a fluid: flowing water, blowing wind (air is a fluid), and ice movement by glaciers (also a fluid). The viscosity of the fluid determines what size of particle will be moved. Because of its low viscosity, wind will only move clay to sand size particles. Glacial ice, on the other hand, has a very high viscosity and can move house-size rocks. The particle sizes moved by water falls in between the extremes of wind and glaciers.

no
Possibly, silt (including clays), sand and gravel. Which are all probably defined by particle size.
Quarks are considered to be fundamental particles, and as such they do not really have a classical "size". Their masses can be compared, however, and they are not the same for all types of quarks.
Sand particles are in fact a variety of sizes on the same beach front. This is because these sand particles are formed at different times through different processes.
False! Not all chemical reactions take place at the same rate.
Sometimes you can see them and sometimes not. It all depends what the particles are made of and their size.
No, all plates are not the same size
No, all plates are not the same size
They are both sedimentary rocks (rocks composed of solidified sediment particle matter), the only difference is that sandstone is composed of sand-sized particles, which are bigger than the silt particles which make up siltstone.
Filtration will remove ALL solid particles regardless of their size. To separate materials based on the size of their particles one would use a process of sieving, using a sieve stack with a smaller and smaller mesh size.
No, they are not.
