A parcel of unsaturated air with a temperature of 30°C rises from the surface to an altitude of 1000 metres. Which of the following describes the temperature of the unsaturated air parcel at this altitude?
A)6°C colder than at the surface
B)6°C warmer than at the surface
C)10°C colder than at the surface
D)10°C warmer than at the surface

Question

Quizplus · Accepted Answer

The temperature of unsaturated air decreases by approximately 1°C for every 100 meters it rises, known as the dry adiabatic lapse rate. Therefore, rising 1000 meters would result in a temperature decrease of about 10°C.
