Denser air sinks replacing less dense air.
It is wrong to say that cold air sinks and hot air rises because it doesn t. That s because the buoyancy of air its ability to rise is dictated both by its. Because of this the molecules in hot air tend to be further apart on average giving hot air a lower density. The idea that the temperature will affect the circulation of atmospheric pressure can also be attributed to the earth s coordinates.
Why does cold air go down and warm air go up. You may have once learned that warm air rises and cool air sinks but that doesn t always hold true. The cold dry air that sinks becomes warmer and dries out leading to the rise of hot air once again. Hot and cold air currents power the weather systems on earth.
