A fire makes things hot. Above a fire, you get quite a lot of hot air. Hot air is less dense than cool

air, so it rises. Because there is quite a lot of hot air, it makes quite a big wind current as it rises,

and that drags the smoke particles upward with the air, in much the same way as wind can raise

dust. Some of the smoke particles are very small indeed, so they can be held up in the air for quite

a long time, and they do not settle out from the air until a long time after they leave the fire, and

usually some distance away from the fire.

In a large bushfire, all the hot air produced makes very strong currents indeed, and not only fine

particles, but also quite large burning twigs and leaves can be carried up in the smoke, and do not

fall out until they have travelled quite some distance. It is these pieces of burning vegetation --

called "embers" -- that often start secondary fires, and make fighting large bushfires extremely

difficult and dangerous.

Why does smoke from burning materials rise in the air?

Smoke rises in the air due to the difference in temperature between the smoke and the surrounding air. When materials are burned, the heat causes the air inside the smoke to expand, making it less dense and causing it to rise. This process creates air currents that carry the smoke upwards.

Science Why smoke particles move about in air?

Smoke particles are very small and light, allowing them to be easily carried by air currents. Additionally, the heat from the source of the smoke causes air to rise, carrying the smoke particles along with it. As the smoke particles cool down, they eventually settle back down due to gravity.
