Answer:
Adiabatic stability
Explanation:
Adiabatic stability - Adiabatic implies a situation in which the air parcel and the surrounding region do not exchange heat. It will ultimately undergo cooling whenever a parcel of air increases. Latent heat does not release whenever unsaturated air parcel moves in an upward direction.
Cooling will occur quickly as air parcel is unsaturated, the cooling is at a rate of 10 °C / km. This is called the dry adiabatic rate of lapse. Once the parcel of air becomes sufficiently dense it will start sinking.
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True, because it happens with landslides and other causes.
No fossils from the Precambrian era have been found because there were no organisms at the time: False because there were organisims like algae and bacteria, and there are a very small amout of fossils from that era.
