Answer:
Cool air falls, this is associated with greater pressures areas.
Warm air rises, this is associated with low-pressure areas.
<u>Explanation:</u>
Due to the <em>differences in air pressure</em>, <em>the wind is blown from 'one location to another location'</em>. The cool air is denser than warm air hence the cool air fells which has high density. The warm air has less density and it rises. So the cool air is related to greater pressure areas and warm air is related to lower pressure areas.
