This is one of the three main types of rocks, one in which fossils are frequently found. These are layers of rock within which are characteristics that are different from layers surrounding it. This is a solid substance that is composed of minerals. This is the type of rock formed by the cooling of molten magma. This is the type of rock formed when they are subjected to higher temperatures and pressures which changes its mineral makeup This is a solid, inorganic substance with a crystalline structure that is formed through geological processes. This is a solid in which the basic unit is packed in an ordered, repeating pattern. This is is an underground layer of water-bearing permeable rock from which groundwater can be easily extracted using a well. This system identifies the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. This is a characteristic of minerals. It describes the mineral's resistance to fractures or scratches. This is the color a mineral leaves behind after being dragged across an unweathered surface. This is a description of the way light interacts with the surface of a crystal, rock, or mineral. This is when minerals break on specific planes. This is the separation of a material into two, or more, pieces under the action of stress.
