how does the decrease in temperature with increasing altitude lead to ...
Generally, temperatures decrease with increasing height because the atmosphere distributes itself according to gravity: Pressure generally decreases with height because the pressure is determined by the mass of the atmosphere above some point. At the surface, the entire mass of the atmosphere is above you bit as you go higher and higher, the amount of atmospheric mass above you decreases, so the pressure falls with height.
The temperature decreases with height in the lowest 10-20 km of the atmosphere (called the troposphere) because most of the solar radiation passes through the atmosphere with little or no effect - that radiation is absorbed by the solid Earth surface and is transferred to the air above the surface by conduction. Conduction is a relatively slow process that by itself would require a long time to transfer that incoming solar energy upward, so the temperature in the troposphere decreases with height.
Above some point, however, another process causes temperatures to become nearly constant with height or even to increase with height. This is because of the absorption of some solar energy by ozone in the air in the next major layer of the atmosphere: the stratosphere. The transition between the troposphere and the stratosphere is marked by an abrupt change from temperatures decreasing with height in the troposphere to remaining nearly constant or increasing with height - the transition is called the tropopause.
