Because the gasses that comprise the flame are lighter than air.

The flame is burning energy, so the flame needs to live off of that energy. The flame rises upward mainly because its like a vacuum the only thing it does is take energy where up is oxygen and other materials the flame can use.

my stab in the dark is that i would think its beacuse most of the gasses and such of burning are lighter than aie so as they drift upward the falme is drawn upward to consume trace amounts
in 0 g though a flame is a ball

Flame is hot burning gas(es) which is lighter than the specific weight of surrounding gas(es).
The lighter gas (flame) goes up due to the pressure exerted by the surrounding heavier gas.

Because flame is actually burning chemicals, and these extremely hot chemicals are rising because they are expanding from the heat, and thus less dense than air.

Gravity. warm air is lighter than chilly and could glide up wards. it relatively is why a flame is blue on backside and crimson on acceptable the less warm extra dense heavy air is on the backside and the hotter air is on the acceptable.

Hot light air rises because the cooler denser heavier air around it pushes it upwards.
