Question 1247Navigation General

The correct answer is D) Red. On a weather map, the line that represents a warm front is typically drawn in red. This is a standard convention used in meteorology to differentiate the different types of fronts on weather maps. Warm fronts indicate the boundary between a warm air mass moving in and displacing a cooler air mass, and the red color is used to visually distinguish this type of front. The other answer choices are incorrect because blue is used for cold fronts, alternating red and blue is used for occluded fronts, and purple is not a standard color used to depict fronts on weather maps.
