Which of the following represents the slope of a warm front?

Correct Answer: Option D — 1 mile vertically to 150 miles horizontally

Warm fronts have a gentle slope, typically rising 1 mile vertically for every 150 miles horizontally. This gradual incline causes warm air to rise slowly over the retreating cold air mass, resulting in widespread cloud cover and steady precipitation, which is a fundamental concept in maritime meteorology and weather analysis.
