The bulk of gaseous interchange in soils takes place by _____. A)mass flow B)partial pressure of N₂ C)diffusion D)dissolution in water E)respiration

Question

Quizplus · Accepted Answer

The primary mode of gaseous interchange in soils is diffusion, which is the movement of gas molecules from areas of high concentration to areas of low concentration. Mass flow is the movement of gases with water through the soil, but this is a secondary mode of gas exchange. The partial pressure of gases may influence diffusion, but it is not the primary mechanism. Dissolution in water may occur, but it is not a major form of gas exchange in soils. Respiration is a biological process that occurs in living organisms and is not directly related to gaseous interchange in soils.
