7. what could have happened to the air parcel to cause rainfall on day 1?\na the air parcel was at the same low temperature as the surrounding air, so it had low energy.\nb the air parcel was warmer than the surrounding air, so it gained energy.\nc the air parcel was warmer than the surrounding air, so it lost energy.\nd the air parcel was cooler than the surrounding air, so it gained energy.
Answer
Brief Explanations:
For rainfall to occur, an air - parcel often needs to rise. Warmer air is less dense and more likely to rise. When an air - parcel is warmer than the surrounding air, it has buoyancy and can rise. As it rises, it cools and the water vapor in it can condense to form clouds and eventually rainfall. Also, when a warmer air - parcel is in contact with cooler surroundings, it loses energy through processes like heat transfer.
Answer:
C. The air parcel was warmer than the surrounding air, so it lost energy.
