The radiative heat of sunlight reaching the surface of the planet is what drives these dust storms. As sunlight hits the ground, it warms the air closest to the surface, leaving the upper air cooler. As in thunderstorms on Earth, the warm and cool air together become unstable, with warm air rising up and taking dust with it.
A meteorological phenomenon, dust storms are common across semi-arid and arid regions of the world. When strong winds, also known as gust fronts, blow loose dirt and sand from the dry land surface, it results in a dust storm.

Are dust storms a suspension?
Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface. Fine particles are transported by saltation and suspension, a process that moves soil from one place and deposits it in another. Drylands around North Africa and the Arabian peninsula are the main terrestrial sources of airborne dust.
Why can’t we say that dust is a suspension?
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.
