15. The locations of the boundary are shown below:

24 29

16. A warm front is present in the top map, as indicated by the red symbol.

17. The front is advancing in the southerly direction, as the warm air behind the warm front is rising over cooler air ahead of the front. So the direction of wind behind the front suggests that the front is advancing from south to north.

18. A cold front is present in the bottom map, as indicated by the blue symbol.

19. The front is advancing in the northwesterly direction, as the cold air behind the cold front is replacing warm air ahead of the front. So the direction of wind behind the front suggests that the front is advancing from northwest to southeast.
