I think the dust in air is neither a colloid, a suspension nor a solution.
REASONS:
1. You can not say that it is a colloid because the common characteristic of a colloid is sticky like lotions and gels;
2. You can not say that it is a suspension because if it is, we should be able to identify easily the solid particles in the air which is the dust;
3. You can not say that it is a solution because it should form only liquid phase as result.
Though I don't think is it is a colloid, a suspension, or a solution, I am sure that it is MIXTURE.
Snow is considered a suspension. It consists of water (in the form of ice crystals) and air, along with tiny particles like dust and other impurities. The solid ice crystals are suspended in the air, which distinguishes it from a solution where one substance completely dissolves in another. In a colloid, the particles are dispersed but not fully dissolved, which is not the case with snow.
Air is neither a colloïd solution nor suspension. It is quite the opposite: a homogeneous mixture, like ALL gases do: there is only ONE existent gas phase .
Yes, suspended silt would count as a colloid.
The mixture of gases in the atmosphere is not considered a solution, suspension, or colloid because gases are uniformly distributed and do not form distinct phases in the atmosphere. It is more accurately described as a homogeneous mixture of gases known as air.
Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds. If there is water or air flowing though the sand at a fast rate, then it can also be a suspension.
colliod
Smog is considered a colloid. A colloid is a mixture where one substance is evenly dispersed throughout another. In the case of smog, tiny particles of pollutants and gases are suspended in the air, creating a colloid. This is different from a suspension, where larger particles are suspended in a liquid or gas but eventually settle out due to gravity.

Yes
Soot in the air is considered a suspension colloid. It consists of fine particles that are dispersed throughout the air but not dissolved in it, allowing them to remain suspended for extended periods. Unlike a solution, where substances are fully dissolved, in a colloidal suspension, the particles can scatter light, which is characteristic of colloids.
It is a suspension of dust particles in a mixture of gases. The latter may be considered a solution of other gases in nitrogen.

Yes, suspended silt would count as a colloid.
air is a solution
No. Except for dust storms.
