Mineral Properties
the color of the powder a mineral leaves behind when you scratch it on a ceramic tile
What is streak?
the kind of rock that forms through the cooling and hardening of molten rock
What is igneous rock?
the process of breaking down of rocks by wind, water, ice, or plants; it can be physical or chemical
What is weathering?
a material that makes up rocks; it is always inorganic, solid, and natural; has a fixed chemical formula, and has a crystalline structure
What is a mineral?
the scale used to measure the hardness of a mineral
What is the Mohs Hardness Scale?
the relationship between the mass of a mineral compared to its volume
What is density?
the broken down particles of rock
What are sediments or clasts?
a mineral that breaks with cleavage in thin layers and is used in makeup
What is mica?
the shine of a mineral; it can be described as metallic or non-metallic
What is luster?
the breakage of a mineral in a jagged, uneven way
What is fracture?
the movement of weathered rock and soil from one place to another by water, wind, waves, glaciers, or gravity
What is erosion?
a mineral with high density (high specific gravity), great 3D cleavage, and silvery metallic shine
What is galena?
the hardest mineral on the Mohs Hardness Scale; used in jewelry and cutting tools
What is diamond?
the type of erosion caused by gravity.
What is mass movement or mass wasting
a mineral known for fizzing when vinegar is applied; it is found in limestone and marble
What is calcite?
The property of a mineral that describes its density compared to the density of water (1 g/ml).
What is specific gravity?
the dropping of sediments by erosion
What is deposition?
a very soft mineral that is used in baby powder.
What mineral is talc?
