The air in the atmosphere circulates mainly because _____.
conduction is absorbing cold air into hot air radiation is emitting the Sun's heat convection is redistributing heat the temperature is uniform around the earth
The answer is convection is redistributing heat. Convection as warm air goes up and once it is cooled it goes back down again. Cool air is more heavy than warm air because it is more dense. Its particles are more closer together than warm air.
