Quizplus · Accepted Answer

In a rising unsaturated thermal, the parcel temperature decreases at a rate of approximately 10 °C per 1000 meters. However, the rate at which the dew point temperature decreases is typically slower, around 1-2 °C per 1000 meters. This is because as the parcel of air rises and expands, its relative humidity decreases, causing the dew point temperature to decrease at a slower rate. Therefore, the correct choice is C, which states that the dew point temperature decreases at a slower rate than the parcel temperature.
