To determine the direction of air movement based on the temperatures given (x22, y18, and z18), we need to identify which area has the higher temperature. In this case:
- Area x has a temperature of 22°C.
- Area y has a temperature of 18°C.
- Area z also has a temperature of 18°C.
Air generally moves from areas of higher temperature to areas of lower temperature. Therefore, air will move from area x (22°C) to the areas with lower temperatures, which are areas y and z (both at 18°C).
Completing the statement:
"Air will move from x (22°C) to y (18°C) and z (18°C)."
