Air moves from areas of higher temperature to areas of lower temperature. Based on the provided temperatures:
- Area X: 22ºC (highest)
- Area Y: 18ºC
- Area Z: 18ºC
Air will move from area X to area Y or area X to area Z, as both areas Y and Z are cooler than area X. However, since the question asks for the movement to a specific area with a lower temperature, the correct response based on the options given is area X to area Y or area X to area Z.
However, if we have to choose one option from the provided list, it would be area X to area Z (considering that area Z is still a cooler area, despite equal temperatures with Y).
So, the answer would be:
area X to area Z
