Its chemical composition is different from iron, possibly hydrogen and helium at severe pressure contact with the outer core which fuses with this layer making it anomalous and viscose where a heat transfer process occurs through convection. In this area the resistance friction initiates from the rotation of the solid Earth

The Mineral Content of US Drinking and Municipal Water Pamela Pehrsson, Kristine Patterson, and Charles Perry USDA, Agricultural Research Service, Human Nutrition Research Center, Nutrient Data Laboratory, Beltsville, MD Abstract The mineral composition of tap water may contribute significant amounts of some minerals to dietary intake. A mineral substance is a naturally occurring solid that has been formed by geological processes, either on earth or in extraterrestrial bodies (Nickel 1995a). A mineral species is a mineral substance with well-defined chemical composition and crystallographic properties, and which merits a unique name.
