What is the most common type of intrusive igneous rock that we've studied?
What is granite
100
Clastic, organic, and chemical
What are the three types of sedimentary rock?
100
type of metamorphic rock in which the mineral grains are arranged into bands.
What is foliated
100
Basalt is what type of rock?
What is igneous.
200
Granite is composed of what three minerals?
What are feldspar, mica, and quartz.
200
Name two igneous rocks other than granite
What is pegmatite, obsidian, basalt, scoria
200
The process of wearing down rocks by wind, water, sand, gravity, and sunlight.
What is weathering?
200
Sedimentary shale, if exposed to enough heat and pressure, will become what rock?
What is slate.
200
shale is what type of rock?
What is sedimentary
300
Rocks that are darker in color, rich in magnesium, calcium, and iron.
What are mafic rocks?
300
Rocks that are lighter in color, rich in aluminum, potassium, silicon, and sodium.
What is felsic?
300
What forms when bits of rock and other materials are cemented together with dissolved quartz or calcite?
What is clastic sedimentary rock.
300
What do scientists call the process of a rock changing shape because it is under so much pressure?
What is deformation
300
Metamorphism that occurs when rock comes within close range of magma
What is contact metamorphism
400
The size, shape, and position of the mineral grains in a rock.
What is texture
400
Extrusive igneous rock that cools so quickly on the surface that no crystals form and it has a vitreous luster.
What is obsidian?
400
In sedimentary rock, the sediments layer upon one another. What are these layers called?
What is strata
400
Metmorphic rocks have gone through this process, which causes a shimmery surface luster.
What is recrystallization.
400
The rock that is commonly classified as organic sedimentary.
What is fossiliferous limestone, fossil sponge, coral are possible answers
500
What length of cooling time is needed to produce large crystals and a coarse-grained texture?
What is long cooling time?
500
This rock is found around the edges of volcanoes. It cools quickly and has little or no crystals
What is scoria.
500
what is a medium grained sedimentary rock that forms when sand grains are deposited in dunes, beaches, or ocean floors and then are cemented together?
What is sandstone.
500
rock that may have once been granite or shale, but because of heat and pressure the minerals are now banded together.
What is banded gneiss
500
Marble is a metamorphic rock that forms when which rock is heated and pressurized.
What is limestone
