This physical property is a minerals ability to reflect light.
What is Luster?
100
This rock forms by applying heat and pressure to all three rock types.
What is a Metamorphic Rock?
100
This igneous rock forms near or above the Earth's surface and generally has smaller crystals.
What is an Extrusive Igneous Rock?
100
This formation was created by magma cooling so quickly that stress fractures formed creating hexagonal columns.
What is Devils Tower?
100
These are beneficial uses of minerals and rocks. (one product and one job)
What are Answers Will Vary?
200
The color of the mineral in a powdered form.
What is Streak?
200
This process forms Igneous Rocks?
What is Magma/Lava Cooling and Hardening?
200
This igneous rock forms beneath Earth's surface and cools more slowly which allows the crystals to grow larger.
What is an Intrusive Igneous Rock?
200

What is Pumice, Obsidian, Granite, Porphyry, Basalt?
300
Minerals that break along smooth, flat surfaces.
What is Cleavage?
300
This rock forms from cementation and compaction.
What is a Sedimentary Rock?
300
This sedimentary rock forms from once living organisms.
What is an Organic Sedimentary Rock?
300
The formation is the result of the deposition of sediments and is shaped by weathering and erosion as well as creating new sedimentary rocks through compaction and cementation.

400
The minerals ability to be scratched?
What is Hardness?
400
This process breaks down all three rocks types into sediments.
What is Weathering and Erosion?
400
This metamorphic rock has mineral grains that line up in layers.
What is a Foliated Metamorphic Rock?
400
This formation is the result of weathering and erosion cutting through the limestone plateau in the northern Black Hills.

What are Definite Chemical Composition, Inorganic, Naturally Occurring, Crystalline Solid?
500
This law states that matter is never created or destroyed?
What is the Law of Conservation of Matter?
500
This sedimentary rock forms from smaller rock fragments compacted and cemented together.
What is a Detrital Sedimentary Rock?
500
These are the two main rock types in the core or center of the Black Hills.
What are Igneous and Metamorphic Rocks?
500
This physical property of a mineral is the ratio of the minerals weight to the weight of an equal volume of water; expressed as number.
