Which clue is directly related to the planetary boundary layer of the troposphere?
Answer and explanation
Correct answer: Effect of surface friction and daily heating
The planetary boundary layer is the lowest part of the troposphere and responds directly to the surface. Friction with the ground slows and mixes the air, while daytime heating creates turbulence and convection; nighttime cooling can produce stable layering. Therefore option A is correct. Gas escape belongs to the exosphere, ion-related processes are associated with higher regions, and the stratopause is not the boundary layer.
