Question

A mineral's hardness is due to chance. Hardness is impossible to predict. a combination of the type of bonding and elements present. a combination of the electrical conductivity and birefringence. the speed of light through the crystal. The smallest unit of a cry stal structure that can be repeated by translation only to create the mineral is called the element. lattice. unit cell. symmetry operation. It would have been unlikely to find minerals such as hematite more than 2.7 billion years ago because there was no blood in early life. water is necessary to create hematite. hematite is a product of plate tectonics. hematite forms with high atmospheric oxygen. An example of a biomineral is: Mineral weathering products of bacteria that use sulfides as energy sources Minerals formed through a biologic process for structural or functional purposes Minerals that form in lab-based processes Minerals that arc both organic and inorganic
