Think of ways scientists could classify different types of matter?. Classification of Gold. At room temperature. 1) Rocks cannot be made of organic material. 2) Luster is classified as metallic and non-metallic. 3) Scientist use tests to identify minerals. 4) Minerals that make up rocks can be mined as ores. 5) A liquid or gas can be classified as a mineral. A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. What are minerals?. Common rock-forming minerals. Physical properties of minerals. Basic rock types. The rock cycle. Minerals .
