Minerals
A naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition.
Mineral
The cooling and hardening of lava or magma
What is the process for making Igneous Rock?
The process for making a sedimentary rock.
What is weathering, erosion, deposition, compaction, cementation?
Exposure to extreme heat and pressure.
What is the process for the formation of a metamorphic rock?
The recycling of rocks.
What is the rock cycle?
Something that cannot form from living things or the remains of living things.
Inorganic
The types of Igneous Rock.
intrusive and extrusive
Forms when rock fragments are squeezed and cemented together.
Clastic sedimentary rock
The arrangement of the grains of a metamorphic rock into parallel layers or bands.
Foliated
Gneiss melts and becomes magma then cools and hardens.
What is the Igneous process?
The color of a mineral’s powder that is produced when rubbing the mineral against a piece of unglazed porcelain tile.
Streak (Test)
Fine grain, course grain or no visible grain.
What are the grain sizes for Igneous Rocks?
Forms where the remains of plants and animals are deposited in thick layers and cemented together.
Organic sedimentary rock
The random arrangement of the grains in a metamorphic rock.
Non-foliated
Granite is weathered into sediment, eroded, deposited, compacted and cemented.
What is the sedimentary process?
A scale ranking ten minerals from softest to hardest; used to compare the property of hardness in minerals.
Mohs Hardness Scale
Granite (intrusive or extrusive?)
What is an intrusive Igneous Rock?
Forms when minerals dissolve in a solution and crystallize.
Chemical sedimentary rock
A foliated metamorphic rock with silent "g"?
Gneiss
Limestone undergoes extreme heat and pressure.
What is the metamorphic process?
The way a mineral looks when it breaks apart in an irregular way.
Fracture
Obsidian (intrusive or extrusive?)
What is an extrusive Igneous Rock?
A clastic sedimentary rock with large, rounded sediments.
Conglomerate
A nonfoliated metamorphic rock used to make statues.
Marble
The Lincoln Memorial is made of this metamorphic rock.
What is Georgia Marble?
