List the 7 tests that are used to identify minerals.
|
-Is a natural occurring solid mixture of one or more minerals, or organic matter.
-Igneous, Metamorphic, and Sedimentary rock.
What is a rock?
What are the 3 types of rock? |
|
Formed in nature
Is solid Is non-living Has a crystalline structure
What are the 4 characteristics that all minerals have?
|
The continual process by which new rock forms from old rock.
What is the rock cycle?
|
|
Mohs Hardness Scale
What is used to determine the hardness of a mineral?
|
-Any type of rock melts into magma, then the magma or lava will cool.
-Intrusive rock is coarse-grained and has large crystals. Extrusive rock is fine-grained and has little to small crystals. Extrusive rock forms when magma gets trapped in a magma pool
How is Igneous rock formed?
What is the difference between intrusive and extrusive rock? |
|
Sub-metallic
Metallic Non-metallic
What are the three types of luster?
|
-Rocks break down by weathering and erosion into sediments. These sediments then go through deposition where they are laid down, finally they are compacted and cemented in to rock.
-Clastic is made of fragments of rock that are cemented. Organic is rock
How does Sedimentary rock form?
What are the key features of Clastic and Organic rock? |
|
The Color test is less reliable because it shows the outside color of the mineral which can always change while the Streak test shows the inside of the mineral which will never change.
What is the difference between the Color and Streak test?
|
-Rocks are in the Earth and are changed by heat and pressure.
-Foliated rock has aligned grains and non-foliated does NOT have aligned grains.
How does metamorphic rock form?
What is the difference between foliated and non-foliated? |
