Why is the saturated adiabatic lapse rate less than the dry adiabatic lapse rate?
What will be an ideal response?
Answer: The dry adiabatic lapse rate is valid for unsaturated parcels and the saturated adiabatic lapse rate is valid for saturated parcels. Once saturation occurs, the latent heat of condensation adds heat to the parcel.

How does the latent heat of evaporation (and its equivalent, the latent heat of condensation) moderate climate?
a) It retards the formation of ice, keeping the oceans warmer. b) By absorbing energy on evaporation and releasing it on condensation, it keeps water cool when the air is hot and warm when the air is cool. c) The endothermic reaction does not allow salt to build up past a certain concentration. d) The latent heat helps generate winds, which help keep the oceans cool when the air is hot. e) It gives water a higher heat capacity, which allows it to stay cool when the air is warm and warm when the air is cool.
