Q.No. 1 (25M)
ATMOSPHERE
TROPOSPHERE: The layer of air immediately adjacent to the earth's surface is called the troposphere. Ranging in depth from about 16 km (10 mile) over the equator to about 8 km over the poles, this zone is where most weather events occur. Due to the force of gravity and the compressibility of gases, the troposphere contains about 80% of the total mass of the atmosphere. Air temperature drops rapidly with increasing altitude in this layer, reaching about -60°C at the top of the troposphere. A sudden reversal of this temperature gradient creates a sharp boundary, the tropopause, that limits mixing between the troposphere and the upper zones.
STRATOSPHERE: The stratosphere extends from the tropopause up to about 50 km. Air temperature in this zone is stable or even increases with higher altitude. Although more dilute than the troposphere, the stratosphere has a very similar composition except two important components: water and ozone.
MESOSPHERE: Above the stratosphere, the temperature diminishes again creating the mesosphere, or the middle layer. The minimum temperature in this region is about -80°C.
