वायुमंडल

वायुमंडल क्या है?

The atmosphere is divided into layers: troposphere (0-12 km, where weather occurs), stratosphere (12-50 km, contains ozone layer), mesosphere, thermosphere and exosphere. The troposphere is thicker at the equator (16-18 km) than at the poles (8-10 km) because tropical heating expands the air column upward. Nearly all weather occurs in the troposphere.
