Final answer:
The type of front that is not found on a weather map is an occluded front.
Step-by-step explanation:
The type of front that is not found on a weather map is the Occluded front. On a weather map, a warm front is represented by red semicircles, a cold front is represented by blue triangles, and a stationary front is represented by alternating red semicircles and blue triangles. However, an occluded front is not typically shown on a weather map because it is a more complex and less common type of front.
