Rock Cycle
100
Shape or texture of a mineral.
What is Form.
100
When a mineral breaks along a smooth, flat plane
What is cleavage.
100
1. Not man made they are found in nature. 2. They are not alive 3. Solids 4. Each mineral has it's own chemical formula
What is the 4 characteristics of a mineral.
100
The breaking down of rocks by plants, water, wind, ice & people.
What is weathering
100
The movement or sediment by water and wind.
What is erosion.
200
Specific gravity
What is the mass of a mineral in relation to water
200
When breakage is irregular, like rough, jagged or curved.
What is fracture.
200
Rocks that are changed/baked by the earth. Formed when heat & pressure cook rocks below the surface making them metamorphic.
What is Metamorphic Rock?
200
No visible crystals (cooled too fast), may have air holes (pores). Examples Obsidian/Pumice.
What are characteristics of extrusive igneous
200
The putting/dropping of sediment into a bed.
What is deposition
300
The mineral's resistance to being scratched.
What is Hardness
300
How a mineral feels (rough, smooth, bumpy, jagged)
What is texture
300
Hot molten rock found below the crust Formed from melted rock in the crust.
What is Magma?
300
Varied sizes of sediment forming layers, may contain fossils. (shale, limestone)
What are the characteristics of sedimentary rock.
300
The hardening of sediment layers into rock by moisture & pressure.
What is cementation?
400
the way light is reflected from the surface of the mineral.
What is Luster
400
Magma Igneous Rock Weathering/Erosion Deposition Cementation Sedimentary Rock Metamorphic Rock Magma (starts over again)
What are the steps of the Rock Cycle in order.
400
Cooled magma found below and above the ground. Formed when heat & pressure push magma to the crust & cooling takes place.
What is Igneous Rock?
400
Mineral bands, flattened crystals (slate)
What are the characteristics of metamorphic rocks?
400
The making of a fossil.
What is fossilization?
500
The color a mineral makes when it is rubbed across a piece of porcelain tile.
What is Streak.
500
Mechanical - done by machines & animals Chemical - done by pollutants like acid rain Physical - by water, wind, ice, plants & other forces of nature.
What are the 3 types of weathering?
500
Hardened layers of moist sediment. Formed when moisture & pressure cement sediment layers into rock.
What is Sedimentary Rock.
500
Interlocking Crystals of varied sizes, may be dark colored & heavy (granite)
What is Intrusive Igneous?
