Sedimentary Rocks
Igneous Rocks
Metamorphic Rocks
The Rock Cycle
100
This describes how a mineral reflects light and includes; glassy, pearly, metallic, and earthy.
What is luster?
100
This is when running water, wind or ice loosen and carry away fragments of rock.
What is erosion?
100
This type of igneous rock forms from the slow cooling of magma inside the earth.
What is intrusive?
100
A type of metamorphic rock that has grains arranged in parallel layers or bands.
What is foliated?
100
What must happen for a rock to become magma?
What is melting?
200
This is the color of the powder of a mineral and is tested by rubbing the mineral on a porcelain tile.
What is streak?
200
This is the process where sediment is glued together to form sedimentary rock.
What is cementation?
200
This type of igneous rock has very fine crystals or no crystals at all because it cooled very quickly.
What is extrusive?
200
The mineral grains in marble and quartzite are arranged randomly and belong to this type of metamorphic rock.
What is non-foliated?
200
Igneous rock forms when this happens to magma or lava.
What is cooling?
300
This property of a mineral is its ability to break easily along flat, plane, surfaces.
What is cleavage?
300
This type of sedimentary rock forms when small pieces of rock are deposited, compacted, and cemented together.
What is clastic?
300
Igneous rocks that are dark in color have a low amount of this substance.
What is silica?
300
When the sedimentary rock called shale undergoes a low grade metamophism it becomes this type of rock commonly used to make chalkboards.
What is slate?
300
This is the first step in a rock becoming a sedimentary rock.
What is erosion or weathering?
400
This property of a mineral is its mass per unit volume.
What is density?
400
This type of sedimentary rock forms when the remains of living things are compacted and cemented together into rock.
What is organic or bioclastic?
400
An igneous rock with a high silica content will be what color?
What is light colored?
400
When the quartz crystals that make up sandstone undergo extreme heat and pressure it becomes this metamorphic rock.
What is quartzite?
400
These two things will change any rock into a metamorphic rock.
What is heat and pressure?
500
This property of a mineral is found by performing a scratch test.
What is hardness?
500
This type of sedimentary rock forms when minerals dissolved in water come out of solution and form crystals.
What is chemical or crytalline?
500
This black igneous rock cooled almost instaneously and therefore has a glassy appearance.
What is obsidian?
500
When limestone undergoes extreme heat and pressure it becomes this metamorphic rock that is often used in statues and buildings.
What is marble?
500
Metamorphic rock that is heated until it melts and then cools and hardens becomes this type of rock.
What is igneous?
