Practice Questions

Question 1

Which gas constitutes approximately 78 percent of Earth’s atmosphere by volume?

Question 2

Under standard atmospheric conditions, at approximately what altitude does atmospheric pressure decrease to half its sea‐level value?

Question 3

In the atmospheric structure, which layer extends from about 50 km to 85 km and is characterized by decreasing temperature with altitude?

Question 4

If the standard lapse rate is $6.5\,^\circ\mathrm{C/km}$ and sea‐level temperature is $15\,^\circ\mathrm{C}$, what is the approximate temperature at $5\,\mathrm{km}$?

Question 5

Given environmental lapse rate $\Gamma_e=4\,^\circ\mathrm{C/km}$, dry adiabatic lapse rate $\Gamma_d=9.8\,^\circ\mathrm{C/km}$, and moist adiabatic lapse rate $\Gamma_m=6\,^\circ\mathrm{C/km}$, how is the atmosphere classified?
