A break in the acetabulumâthe socket located on each side of the pelvisâis less common than other types of pelvic or hip fractures. It usually occurs as the result of a car accident or fall from a significant height, with damage to other bones and soft structures in and around the hip and pelvis.
Diamonds are nevertheless classified as minerals, because they adhere to the five core characteristics of minerals. In addition to being formed by a natural process, minerals are stable at room temperature. This simply means that all minerals are solid at normal temperatures and pressures common on the Earthâs surface. This characteristic excludes water from being a mineral because of its liquid state but includes the solid form of water â ice â as a valid mineral. Minerals are also represented by a chemical composition or atomic structure. Minerals all share a uniquely orderly internal order.
A mineral is a chemical compound with a given composition and a defined crystal structure.[5] A rock is a mixture of one or several minerals, in varying proportions. A rock has only two of the characteristics minerals haveâit is a solid and it forms naturally.A rock usually contains two or more types of minerals.Two samples of the same type of rock may have different kinds of minerals in them.Minerals are always made up of the same materials in nearly the same proportions.est Answer: A mineral is a homogeneous naturally occurring substance with a definite but not necessarily fixed chemical composition. Most minerals are solids with an ordered atomic arrangement, and most are inorganic in the chemical sense of that word Minerals are different from rocks.
