The correct answer is A) Cold fronts are more violent and of shorter duration. Cold fronts typically bring more pronounced weather changes, with sharper temperature drops, stronger winds, and more turbulent conditions compared to warm fronts. This is because cold air is denser and more forceful as it pushes into and displaces the warmer air ahead of it. In contrast, warm fronts tend to create more gradual, less dramatic changes as the gentler, warmer air gradually replaces the cooler air. The other answer choices are incorrect. B) is incorrect because cold fronts are more violent, not milder. C) is incorrect because warm fronts are less violent and of shorter duration than cold fronts. D) is incorrect because there are distinct differences in the weather patterns associated with cold and warm fronts.
