Air moves from areas of higher temperature to areas of lower temperature. In the provided data:
- Area X: 22ºC (highest temperature)
- Area Y: 18ºC
- Area Z: 18ºC
Since area X has the highest temperature, air will move from area X (22ºC) to areas Y and Z (both at 18ºC). However, since the question asks for a specific direction between the options given:
The correct completion is:
area X to area Y or area X to area Z.
If you need to choose from the provided options only, you could say:
area Y to area Z or area Y to area X as both Y and Z have the same temperature.
