  1. F _____ The lifting condensation level is the level at which, if an air parcel is forced to lift to it, it will keep going. 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.

  15. Fig. 5-15, p.121 T _____ Cloud droplets are much smaller than the average raindrop.

  16. Geostrophic wind Fig. 6-19a, p.159 T _____ Surface winds are cross-isobaric, blowing towards lower pressure.

  17. Fig. 4-5, p.81 Fig. 5-20, p.125 F _____ In clouds that are mixed with supercooled liquid droplets and ice crystals, the ice crystals tend to grow, because there are more water vapor molecules surrounding the ice crystals than around the liquid droplets.
