A) Metamorphic
B) Sedimentary
C) Igneous
B) Sedimentary
300
What is the degree to which light can pass through a mineral called?
Transparency
300
What is a naturally occurring, solid, that is inorganic, with a definite chemical composition and crystal structure?
A mineral
400
If a scientist found a rock that was formed from heat and pressure, how would this rock be classified?
Metamorphic
400
A scientist wants to find out what type of mineral she has. What is the best way for her to find out?
A) She could look at the colour, hardness, and luster.
B) She could look at the weight, hardness, and colour.
C) She could look at the colour, weight, and size.

Granite is formed by what processes?
A) Heat and Pressure
B) Melting (molten magma) and Cooling
C) Weathering, Erosion, Deposition, Compaction, and Cementation
B) Melting (molten magma) and cooling
Granite is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.
400
Which of these would be the least useful when identifying a mineral?
A) luster
B) hardness
C) shape
D) colour
C) shape
400
What rock is found in places that have volcanos?
A) sedimentary rock
B) metamorphic rock
C) igneous rock
C) Igneous Rock
Are igneous rocks always formed by volcanoes?
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust.
500
When sediments get compacted and cemented it forms what type of rock?
A) sedimentary rock
B) metamorphic rock
C) igneous rock
A) sedimentary rock
500
A diamond is measured as a 10 on the Mohs hardness scale for minerals. What will happen when a diamond is scraped against a mineral with a lower hardness rating?
A) the diamond will chip
B) the diamond will increase in hardness
C) the diamond will scratch the other mineral
D) the diamond will lose hardness to the other mineral
C) the diamond will scratch the other mineral

When heat and pressure are applied to any rock, it forms what type of rock?
A) sedimentary rock
B) metamorphic rock
C) igneous rock
B) metamorphic rock
500
What is the way minerals reflect light from its surface called?
Luster
500
What rock is found in mountains?
A) sedimentary rock
B) metamorphic rock
C) igneous rock
B) Metamorphic Rock
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
