Q

Describe what happens at a cold front when a cold air mass meets a warm air mass

A

At cold front, cold air pushes under warm air. As the warm air rises, water vapor condenses to form clouds. Cold fronts move quickly, causing strong winds and heavy rains. Thunderstorms often occur along cold fronts. As the cold front passes, the sky clears and the weather gets cooler.

A

Atoms move freely
