The four main layers of the Earth from the surface to the center.
What are Crust, Mantle, Outer Core, Inner Core
Name one characteristic of a mineral.
Inorganic process, crystal structure, definite chemical composition, solid, naturally occurring
The 3 rock types
What are Metamorphic, sedimentary, igneous?
Weathering causes this type of rock to form.
What is sedimentary?
Describe the difference between a coarse-grained rock and a fine-grained rock.
Coarse-grained=large grains that you can see
Fine-grained=tiny grains you need a microscope to see
The thickest layer of the Earth.
What is the Mantle?
Glassy, metallic, earthy, vitreous
What is Luster?
Process that forms an igneous rock.
What is magma/lava that has cooled?
True or false: Rocks always follow the same steps and same order in the rock cycle.
False
Extrusive vs. Intrusive Igneous rocks
Extrusive=formed above ground, magma cooled rapidly
Intrusive=formed below ground, magma cooled slowly
State of matter for the Outer Core.
What is liquid?
The 4 ways minerals can be formed.
Organic Minerals, minerals from solutions, minerals from magma/lava, altered minerals
Processes that form a sedimentary rock:
What are weathering, erosion, deposition, compaction, cementation?
Below Earth’s surface, heat and pressure form this rock.
What is metamorphic?
Name one difference between a rock and a mineral.
Answers will vary
Hottest layer of the Earth.
What is the Inner Core?
Properties of minerals to determine what type it is. (Name 4)
Streak, luster, color, density, crystal structure, hardness, cleavage and fracture, special properties
Changes a rock into a metamorphic rock.
What is heat and pressure?
Name the two steps that form sedimentary rock AFTER deposition.
What are compaction and cementation?
Hardness based on Moh’s Hardness scale when a mineral can’t be scratched by fingernails, glass, pennies, or a steel nail.
What is 7 or higher?
Process in which rocks are heated in the outer core, rise through the mantle, and sink back down.
What are convection currents?
Hardness of a mineral you can scratch with your fingernail.
What is 2.5 or less?
This type of rock (igneous, sedimentary, or metamorphic) and where it formed, above or below earth’s surface.
What is intrusive Igneous, formed below earth’s surface?
Draw a diagram of the rock cycle with labels of the types of rocks and the processes that change them.
Name one coarse-grained rock you know about and identify any minerals that might make up this rock.
Ex. Granite-quartz, mica, feldspar
