|---|---|---|
|
They are nonliving, they have a crystalline structure, they are a solid, and is formed by nature.
What is the 4 characteristics that all mineral have?
|
Cooling, melting, compaction and cementation, heat and pressure, and weathering and erosions.
Describe the five processes that are occurring in the Rock Cycle?
|
Crust- where we live.
Mantle- is a hot liquid layer between the crust and core. Core- solid,dense layer in the center of Earth.
What are the 3 composition layers of the Earth? ( from outside to inside) And what are they like?
|
|
Luster, cleavage and fracture, hardness, density, streak, color, and other properties.
What are the 7 different tests that can be performed in identifying minerals?
|
Fine grained igneous rock is made out of tiny minerals. Coarse grained igneous rock is made out of thick minerals.
Igneous rock can be fine grained or coarse grained. Explain who their how their formation is different.
|
Lithosphere- solid outer layer ( crust, hard upper part of the mantle)
What are the 5 layers of the Earth by physical properties? ( from outside to inside) And what are they like?
|
|
A scale to measure the hardness of a mineral.
What is Moh's Hardness Scale?
|
In the ocean; on the sea floor.
Where is sedimentary rock formed?
|
|
|
You scratch the mineral with a streak plate.
How do we use it?
|
Heat and pressure
What two things are needed to form metamorphic rock?
|
|
|
No because minerals make up rock.
Is a mineral a rock?
|
Igneous rock is formed in a volcanic eruption.
Where is igneous rock formed?
