Quizplus · Accepted Answer

When a dry air parcel rises due to surface heating, it cools at a rate of around 10°C per 1000 meters. If this cooling rate is slower than the surrounding air, the parcel is warmer and lighter than its surroundings, and it will continue to rise. This leads to unstable atmospheric conditions, which can result in thunderstorm formation and turbulent weather. Therefore, a dry air parcel rising due to surface heating is considered to be unstable.
