Motion of Soil Air

Conditions of a Healthy Home

Subjects > Health > Healthy Dwelling Houses
It is important to observe that the air in the soil is in continual movement. This movement is especially active in dry, porous soils. The motion of the air in the ground is caused by pressure of the atmosphere and wind against its surface; by changes in the temperature of the lower strata of the atmosphere and of the upper surface of the soil, by the rainfall, and by changes in the level of the ground water; and to some extent by the operation of the law of diffusion of gases.

Other important things to consider:

• Sources of polluted ground-air
• Motion of Soil Air
• Closing of Ground-Pores
• Current in Ground-Air
• Coal-Gas In Dwellings
• Features of a Healthy Home Site
