Pedogenesis (from the Greek pedon, soil) is the whole process by which weathered rock, the parent material, is turned into soil through the action of climate, organisms, relief and time.

Biogenesis refers to life arising from pre-existing life. Biodegradation is the breakdown of organic matter by organisms. Biomagnification is the build-up of toxicants along a food chain. None of them names the formation of soil.
