Aero III Unit 1 Review

Instability is an atmospheric condition in which (a)   .

• air tends to rise easily

• two air masses of equal strength meet

• a thunderstorm is located within clouds

• atmospheric pressure is too low

Convection creates patterns of (a)   in the atmosphere and water in the ocean.

• energy and radiation

• rising and sinking air

• hot and cold vapor

• wind and precipitation

All weather is the result of (a)   .

• temperature change
• air humidity

• heat exchange
• cloud formations

The rate at which temperature decreases as (a)   is known as adiabatic lapse rate.

• moisture condenses

• altitude increases

• clouds evaporate

• wind increases
