Frontal precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature. Along the fronts, the warm air rises above the denser cold air. The mid-latitude regions experiencing the convergence of warm tropical and cold polar air masses are important areas receiving frontal precipitation.
According to Alfred Wegener, all the major continents formed one giant supercontinent, called Pangaea. About 200 million years ago, the supercontinent Pangaea began to rift.
