Delhi UMET/DPMTDelhi UMET/DPMT 2008
Solution:
Stratosphere extends from $8-16$ to $30-50\, km$. Temperature shows a gradual increase with increase in altitude. It includes much of ozone Saver. Troposphere is nearest to earth. in this. Temperature drops to $-56^{\circ}C$ by the time of an altitude of about $16-18\, km$ is reached. Mesosphere, above stratosphere, extends roughly to $80\, km$ and its temperature drops $-2^{\circ}C$ to between -80 and $ -94^{\circ}C $ at the mesopause, Atmosphere is a insulating of air around the earth.
