The vertical rising or sinking of air is known as the air current
When the air moves it is called an air current or wind
A current of cool air is called a draft.
Convection current
An upward moving current of air is called an updraft.
there are four options 1. wind 2. air current 3. air turbulence 4. air mobility
A convection current is not a technological term; it is a term used in Science for talking about air current. A convection current is the cycle of hot air going up, and cold air going down.
yes, a current of air forced backwards causes the air craft to move.
A convection current in air will have warmer air near to the heat source and this will rise. Then it gradually loses heat to the surroundings and sinks again, so there is warmer air in parts of the current and cooler air in other parts.
It's known as a convection current not a conduction current :)
The current for a hot air balloon is to feel windSlide down for more
it is a thermal current
