Interpretive Summary: How does weathered rock become soil? This letter is in response to an article that allows extending the concept of soil to moons or planets that do not have anything living. This letter shows how plants or other living input are needed to form weathered rock and sediment into soil. This is of interest to scientists.
Technical Abstract: Unconsolidated material does not become soil without biological input. Until it is proven that life forms exist on extraterrestrial planets and moons, these should not be considered "soils" in context of soil formation, which includes the organism factor. There is already a perfectly good term for weather rock: regolith. Many studies describing early soil formation show the necessity of biological input.
