According to a weather map, a cold air mass is moving into a given area where a warm air mass is currently located. What type of weather should be expected as the cold air mass approaches?

A tornado. Tornadoes are formed when hot air and cold air meet in a powerful storm, and the warm air begins spiraling upward, creating a funnel cloud. This funnel cloud forces objects on the ground and in the air around and upward, and can be strong enough to uproot trees, move cars and tear apart buildings.
