he action of warm air rising and cold air sinking plays a key role in the formation of severe thunderstorms. If the warm surface air is forced to rise, it will continue to rise, because it is less dense than the urrounding air. In addition, it will transfer heat from the land surface to upper levels of the atmosphere through the process of

E upwelling.

1 answer

The correct answer is D: convection.

In the context of severe thunderstorms, the warm surface air rises due to being less dense than the cooler surrounding air. This rising warm air helps to transfer heat from the land surface to the upper levels of the atmosphere primarily through the process of convection, which involves the movement of heat through fluid (air being a fluid in this case) as it circulates.
