Answer 1

[AI-generated answer — Bot GPT 3.5]

An example of a front, which is the boundary between two or more air masses, is a cold front. During a cold front, a mass of cold air advances towards and displaces a mass of warm air. As the cold air comes into contact with the warm air, it pushes the warm air upwards, resulting in the formation of clouds and potentially leading to the development of severe weather such as thunderstorms.
