I'm the color of the mineral powder that is left behidn when a mineral is scraped across a surface | streak |
I'm the molten rock inside Earth. | magma |
I'm a solid formed in nature with a definite chemical makeup and a crystal structure. | mineral |
I'm the way in which light reflects from the surface of a mineral. | luster |
I'm the molten rock that reaches Earth's surface | lava |
I'm a substance that contains only one type of atom. | element |
I'm the tendency of a mineral to break along flat surfaces. | cleavage |
I'm a solid in which the atoms are arranged in an orderly, repeating three-dimensional pattern. | crystal |
I'm the tendency of a mineral to break into irregular pieces. | fracture |
I'm a mineral's resistance to being scratched. | hardness |
I'm rocks that contain enough of a valuable mineral to be mined for profit. | ores |
I'm the mass of a substance divided by its volume. | density |
For a mineral to display this characteristic, the atomic bonds are weaker in the direction in which the crystal breaks. | cleavage |
All samples of a mineral will show this same characteristic, even if they look completely different. | streak |
This material contains all the types of atoms found in minerals, and many minerals grow from it. | magma |
This characteristic is often measured according to Mohs scale, in which talc has a value of 1 and diamond a value of 10. | hardness |
Strip mining, open-pit mining, and deep mining are all methods of removing these rocks taht contain large amounts of a desired mineral. | ores |
This substance is always made up of the same elements in the same proportions. | mineral |
