Answer:
C. dry adiabatic lapse rate
Step-by-step explanation:
- When a parcel of air cools down its due to the rising from the adiabatic lapse rate processes. At a rate of 10 C/Km as the dry adiabatic lapses rate minuses the heat added by the latent heat of condensation.
- This the parcel of air has to expand and then cool and thus its density gets reduced. Thus occurs as the air pressure decreases the parcel with an increase in height.
