Explanation:

Explanation: In a cold front, the cold air mass will be advancing and under cutting the warm air. The gradient of the cold front is usually much steeper than that of the warm front and the rapid ascent of warm moist air at the front causes rapid cooling, condensation and the development of cumulonimbus clouds. In a warm front, the warm air mass will be advancing and overriding the cold air.
