Heat always rises. Hot air is lighter than cold air. That's science baby.
Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.
Fire points up due to convection, where the hot air rises and cooler air sinks. This creates a continuous flow of air that carries the flames upwards. Additionally, the shape of the flame is also influenced by gravity, which tends to pull the fire upward as it burns.
Light changes direction when it goes into a glass block and exits out because it refracts due to the change in medium.
Fire whirls work in a manner somewhat similar to dust devils. The intense heat produced by a fire will always generate an updraft. As air flows into the fire it may gain some spin as it interacts with vegetation and topography. This spin can then be taken on by the updraft, producing a vortex of smoke and flames.
The force that opposes gravity and causes objects to move upward is called lift. Lift is generated by the flow of air over the wings of an aircraft or other aerodynamic surfaces, creating a pressure difference that pushes the object upward.
Because light air moves up
Fire burns upward. So if you are standing upright or running, you may fan the flames with air and the fire will spread to your face. Good luck preventing it!

(in my case a kite) but all seriousness fire works
Yes. Fire goes upward precisely because Earth's gravity pulls things downward. The fire is lighter (less dense) than the air that replaces it, so the air pushes the hot air from the fire upwards.
Flames are the gasses of combustion, heated to the point of glowing. Hot gasses, being less dense and therefore lighter than cold gasses (surrounding air) rise upward until they are redirected by some solid object.
Gravity pulls it down.
Fire moves upward due to the natural convection process. As the fire heats the surrounding air, it becomes less dense and rises, creating a flow of air upwards. This convection current carries the flames and heat upwards, which is why fire tends to move in an upward direction.
An ascending tract goes upward. The descending tract goes downward.
the fire goes out
Heat rises so the draught pulls the flame up
Fire points up due to convection, where the hot air rises and cooler air sinks. This creates a continuous flow of air that carries the flames upwards. Additionally, the shape of the flame is also influenced by gravity, which tends to pull the fire upward as it burns.
