Experts say this has encouraged an illegal trade, potentially endangering South Africas remaining wild lions. Because clouds move, they often transport water to locations far from where the water originated. Microbiological decomposition leads to the production of carbon dioxide and its content increases in the soil air. It also buffers against pollutants, thus protecting groundwater quality. Aggregates also provide pore space for water and air to enter the soil, allowing plant roots to grow.) The partial pressure of a gas in a mixture is simply the pressure the gas would exert if it was present alone in the volume which has been occupied by the mixture of gases. We build on soil as well as with . Gaseous exchange between soil and atmosphere takes place by diffusion and mass flow as follows: Mas flow of air is apparently due to pressure differences between the atmosphere and the soil air and is relatively unimportant in determining the total exchange that occurs.
