At the earth’s surface, the soil material is not present as a continuum, but in the form of soil particles. These particles are granular and consist of inorganic material.

Humidity indicates the proportion of water vapour in a gas mixture. Since gases cannot absorb an unlimited amount of water, the relative humidity, on the other hand, describes the actual water content in relation to the physical maximum of a gas mixture.
Carbon monoxide is a chemical compound made up of carbon and oxygen. The molecular formula is CO. Carbon monoxide is odourless and colourless and very toxic. It is formed during the incomplete combustion of carbon-containing substances.
