Which of the following best defines a mineral and a rock? A. A rock has an orderly, repetitive, geometrical, internal arrangement of minerals, a mineral is a lithified or consolidated aggregate of rocks. B. A mineral consists of its constituent atoms arranged in a geometrically repetitive structure; in a rock, the atoms are randomly bonded without any geometric pattern. C. In a mineral the constituent atoms are bonded in a regular, repetitive, internal structure; a rock is a lithified or consolidated aggregate of different mineral grains. D. A rock consists of atoms bonded in a regular, geometrically predictable arrangement, a mineral is a consolidated aggregate of different rock particles The size, shape, and distribution of the particles that collectively constitute a rock is termed......

A main mechanism through which rocks melt in which a body of rock is held at approximately the same temperature, but the pressure is reduced. A. Plume melting. B. Decompression Melting C. Flux melting. D. Magmatic melting. A source of heat that involves the fission of atoms or the spontaneous breakdown of some atoms or elements. A. Convection B. Radioactivity. C. Radiation. D. Conduction. According to....... concept, minerals crystallize in a predictable order. Some minerals crystallize at relatively higher temperature. At successively lower temperatures, other minerals begin to crystallize. A. Magmatic differentiation B. Crystal settling. C. Geothermal gradient. D. Bowen's reaction. Bowen's reaction series is applicable to igneous, sedimentary, and metamorphic rocks. A. True. B. False. Mixing of magmas and partial melting form mainly felsic minerals in the magma. A. True. B.
