which condition causes storms to occur?\no freezing of water droplets\no sudden change in air pressure\no…

Brief Explanations:

Storms are often triggered by a sudden change in air - pressure. A pressure gradient force is created when there is a significant difference in air pressure over a short distance. This force causes air to move rapidly, leading to storm - related weather phenomena like strong winds, thunder, and lightning. Freezing of water droplets is related to formation of ice in clouds but not the main cause of storms. Condensation of water vapor forms clouds but not directly storms. Rapid heating of the upper atmosphere is not the typical cause of storms.

Answer:

sudden change in air pressure
