_____ The lifting condensation level is the level at which, if an air parcel is forced to lift to it, it will keep going Temperature (°C) Height above the ground (m) level of free convection Dew point lifting condensation level F If you were marked wrong for marking this one “F,” please turn back your quiz to me after class so that you can get a point for it.
