the presision of heat and the sun sets charge lol not true
Actually, cool air tends to be more dense and flow under warm air

sink below the surface
The Buoyant Force is the upward force exerted on an object submerged in water. Anything less dense than the liquid it is submerged in tends to float. Anything that is more dense than the liquid that it is in tends to sink.
Warm air is less dense and tends to rise, cool air is more dense and tends to sink. That is why a hot air balloon rises if the air inside is warmer than the outside air.
Density current
No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.No. If you blow air into a baloon, it will be under pressure, and therefore more dense, than the air outside.
density current
Water that is more dense will flow beneath the water that is less dense
As the air cools during the night, it tends to flow downhill.
