Minerals Overview
A rock is a solid mass of ________, or of _________ -like materials.
What are/is Mineral(s)
This is the color of a mineral in powdered form.
What is streak?
This model describes the ways rocks transform from one type to another.
What is the rock cycle?
There is one word that describes the chemical or mechanical breakdown of rock into sediments.
What is weathering?
In The Legend of Zelda, the green-clad hero you play as has this name.
Who is Link?
This mineral characteristic means the atoms are arranged in an orderly, repeating pattern.
What is crystalline structure?
Vitreous, pearly, silky, and earthy are all types of this property, which describes how light reflects off a mineral.
What is luster?
Magma that cools inside the crust forms this type of igneous rock, while lava that cools on the surface forms the other type.
What is intrusive and extrusive?
Compaction followed by cementation turns loose sediments into rock through this process.
What is lithification?
This is the only planet in our solar system not named after a Greek or Roman god.
What is Earth?
In this mineral-forming process, elements in cooling magma arrange into crystals. The slower the cooling, the bigger the crystals.
What is crystallization?
This scale ranks minerals from 1 (talc) to 10 (diamond) by how hard they are.
What is the Mohs scale?
A rock cooled fast enough that its crystals can’t be seen with the naked eye. Name its texture and whether it is intrusive or extrusive.
What is fine-grained, and extrusive?
This type of sedimentary rock forms when dissolved minerals precipitate out of water.
What is chemical sedimentary rock?
A group of crows is called by this slightly spooky name.
What is a murder?
In this process, hot water reacts with existing minerals to form new ones, such as bornite.
What is hydrothermal formation?
A mineral forms cube-shaped crystals but breaks into uneven, irregular pieces. This is the property it is showing.
What is fracture?
A rock contains 36% dark silicates, so it has this composition.
What is andesitic?
(bonus: double points) These are the 3 agents of metamorphism.
What are heat, pressure, and fluids?
In Harry Potter, students catch the Hogwarts Express from this platform number at King’s Cross Station.
What is 9¾
Pyrite (FeS₂) belong to this specific mineral group.
What are sulfides?
A brassy yellow, metallic mineral forms a 1 cm × 2 cm × 4 cm cube with a mass of 40 g. Give its density.
What is 5 g/cm³?
Basalt is buried deep, heated and squeezed without fully melting. Then later, heated enough to melt. Name these two processes in order.
What are metamorphism, then melting?
Heat and direct pressure from colliding plates often produce this type of metamorphic rock.
What is foliated?
This is the only letter of the alphabet that does not appear in the name of any U.S.
