Answer to Question 1

Answer: warm front

Answer to Question 2

Answer: Absolutely unstable air: whenever the environmental lapse rate exceeds the dry adiabatic lapse rate, the air is absolutely unstable and a parcel contained within it will continue to rise once lifted, regardless of whether or not it is saturated. Absolutely stable air: whenever the environmental lapse rate is less than the saturated adiabatic lapse rate, the air will be absolutely stable and will resist lifting, regardless of whether or not it is saturated. Conditionally unstable air: when the environmental lapse rate is greater than the saturated adiabatic lapse rate but less than the dry adiabatic lapse rate the air is said to be conditionally unstable, and the tendency for a lifted parcel to sink or continue rising depends on whether or not it becomes saturated and how far it is lifted.
