Soils consist of organic material, inorganic material, water and air, and they differ in proportions of clay, silt, and sand. A soil profile is characterized by horizontal layers called horizons. Climate, organisms, topography, parent material, and time influence soil composition and formation.

If the flux of material into and out of a given reservoir is the same for some period of time, that reservoir is said to be in a steady state.

It is important to remember that while matter and energy are processed in cycles, they are not necessarily moving in a simple circle and do not really have a beginning or an end. Today, anthropogenic activities are altering all major ecosystems and the biogeochemical cycles they drive.

In 2018, the additional flux of carbon into the atmosphere from anthropogenic sources was estimated to be 36.6 gigatons of carbon (GtC = 1 billion tons of carbon)—a significant disturbance to the natural carbon cycle that had been in balance for several thousand years previously.
