The rocket equation grows delta-v only with the logarithm of the mass ratio, so a single stage hauling empty tanks all the way up is hopelessly inefficient. Staging drops dead weight along the way: each stage contributes ve·ln(mass ratio), and their sum easily clears the ~9.4 km/s needed for low Earth orbit.

The International Standard Atmosphere is the reference model all aircraft and instruments are calibrated against. Temperature falls steadily through the troposphere at 6.5 °C/km, then holds constant in the stratosphere above the tropopause. Pressure and density decay roughly exponentially — at airliner altitude the air is only a quarter as dense as at sea level.
