.........is the rise in the average temperature of the earth atmosphere.
Rashmi P.
In the troposphere (the lowest part of the atmosphere), the temperature decreases rather uniformly with altitude at a so-called "lapse" rate of about $6.5^{\circ} \mathrm{C} / \mathrm{km}$. What are the temperatures (a) near the top of the troposphere (which has an average thickness of $11 \mathrm{~km}$ ) and (b) outside a commercial aircraft flying at a cruising altitude of $34000 \mathrm{ft} ?$ (Assume that the ground temperature is normal room temperature.)
If the air temperature outside a jet airplane flying at 34,000 feet is -40°F, use the average lapse rate to estimate the temperature at sea level below: _____ °F.
