Answers
The correct answer to the above question is as follow -
1. Luster - Pyrite exhibits luster when it reflects light and has a metallic look. Sometimes, the color of pyrite resembles such that it gets its nickname as brass, Brazzle and Brazil.
2. Cleavage - Cleavage is the tendency of any mineral rock to break in a certain definite direction, thus giving its more or less smooth surfaces.
3. Fracture - In some minerals like mica, the forces are strong and the same along with all the directions, so it will not have any cleavage plane, therefore it will break unevenly or get fractured.
4. Hardness - Hardness is the property that is resistant to scratching or any kind of abrasion.
5. Minerals - Minerals and rocks are considered to be the building blocks of rocks.
6. Luster - When a mineral gets in powdered form, the color of the mineral is due to the luster property.
7. Opaque - opaqueness is not the property of a mineral whereas, hardness, luster, and streak are the property of the mineral.
8. Luster - Luster is the property of the mineral by which it reflects light.
9. Mineral - A mineral is a naturally occurring inorganic solid that possessed an orderly crystalline structure and definite chemical composition.
10. Cleavage - Cleavage is the property through which the purity of gold is identified.
11. Aragonite - Aragonite is a carbonate mineral that occurs in a different crystal form and is less common than either calcite or dolomite.
12. Texture - Texture defines the size, shape, and arrangement of mineral grains in rocks.
13. Organic - Mineral is an inorganic naturally occurring crystal structure and is solid.
14. Cleavage - Cleavage is the tendency for a mineral to break along flat surfaces.
15. Crystal - Crystal is the solid form of mineral formed by the repetition of atoms.
