Vocabulary
A substance that cannot be broken down into simpler substances by chemical means.
Element
First step in the rock cycle?
Weathering
What is the baseline scale we use to determine the relative hardness of a mineral?
Moh's Hardness Scale
Explain how sedimentary rock forms
Sedimentary rock is a result of weathering, erosion, deposition and finally compaction and cementations of those grains or pieces of rock.
There are two main types of luster that have many subcategories. What are they?
Metallic and submetallic
The splitting of a mineral along smooth surfaces or in sheets.
Cleavage
Heat and pressure will form this kind of rock that can change its mineral composition
Metamorphic
Streak test
Cooling and solidification forms what type of rock?
Igneous
What is it called when cooled, solidified rock is pushed towards Earth's surface to continue the rock cycle?
Uplift
Reclamation
What is erosion?
The process by which wind, water, ice or gravity transports soil and sediment from one location to another.
All minerals have a specific ________________. Or a ratio of mass to volume that is the same for all samples of a mineral regardless of mass.
Density
Igneous rock has a coarse and fine grained texture that is separated by its color. What is the lighter color called?
Felsic
If you have a mineral that has a known density of 4.3g/cm^3 and you are wondering what its hardness is. Based on its density, would you expect it to be a harder or softer mineral?
Harder. Mineral hardness is directly correlated to a higher density.
A naturally occurring solid mixture of one or more minerals or organic matter.
rock
The size, shape and positions of the grains that make up a rock is called its?
Texture
List (4) special properties of minerals
Magnetism, fluorescence, chemical reaction, optical properties, taste, radioactivity
This is a form of igneous rock formed beneath Earth's surface.
Intrusive
What are the four properties of minerals?
solid, inorganic, naturally forming crystalline structures
The chemical make up of a substance
Composition
Why aren't minerals rocks?
Because minerals make up the composition of rocks.
Calculate the density of a substance that has a mass of 45g and a volume of 9cm^3
5g/cm^3
Diamond formation is a result of pressure that occurs between large pieces of Earth's crust. This kind of metamorphism is referred to as ________________ metamorphism.
Regional
List a possible danger of mines that are not reclamed
They can form giant sink holes.
