What happens in a cold front? A.A cold air mass catches up to a moving warm air mass, sliding over it. B.A warm air mass becomes
a cold air mass as it moves. C.A warm air mass collides with a stationary cold air mass, and slides under it. D.A cold air mass comes in under a warm air mass.
In meteorology (the study of weather), a "front" is the leading edge of an air mass, that's moving in and replacing a mass of a different kind of air. Like warm moving in and replacing cold, or cold moving in and replacing warm.
Remember that cold air is heavier than warm air. So whenever a warm or cold front moves in, the cold air always stays low and the warm air always lifts up over it.
