PRECIPITATION

#19. Showery precipitation occurs from

• ANS
• BAC
• CCB

#1. When supercooled water drops and ice particles co-exist the ice crystals grow at the expense of the water drops because

• ASaturation vapour pressure over water drops is less than over the ice crystals
• BSaturation vapour pressure over the ice crystals is less than over water drops
• CThe ice crystals convert into water drops

#2. The cloud whose tops extend well above the freezing level are called

• AWarm clouds
• BCold clouds
