What are the properties of minerals?
Rocks that are formed from magma under Earth's surface.
What is intrusive igneous rock?
Organic/chemical and inorganic sediments cemented together
What are sedimentary rocks?
Two factors that affect rocks undergoing metamorphism.
What are heat and pressure?
The two most abundant elements in earth's crust.
What are silicon and oxygen?
The physical property described as a way a mineral reflects the light.
What is luster?
An extrusive rock of fine texture that is lower in density
What is rhyolite?
This sedimentary rock is made up of clay sized particles
What is shale?
Rocks that have crystals arranged in layers and bands.
What is foliated rock?
This property describes the size, shape, and arrangement of the crystals or grains in a rock.
What is texture?
This mineral has a hardness of 6, has cleavage, and is pink.
What is Potassium Feldspar?
Texture that forms when magma has a longer time to crystallize.
What is coarse grain?
Two ways in which sedimentary rocks can be classified.
What are composition and texture.
Rocks that are uniform in color and have a random crystal orientation. An example would be marble.
What is non-foliated rock?
The continual changing of rocks into different types of rocks.
What is the rock cycle?
A mineral that salt is processed from
What is Halite?
This rock has a glassy texture, is vesicular, and is mafic in composition
What is Scoria?
The order of the four clasts (grain size) from largest to smallest.
What is pebbles/cobbles > sand > silt > clay?
Metamorphic changes in rocks that occur over a large area.
What is regional metamorphism?
The coolest teacher on the planet
Who is Mrs E?
Examples of silicates (contains SiO)
What are Olivine, Pyroxene, Amphibole, Mica, Feldspar, and Quartz?
This rock is made of plagioclase feldspar, biotite, and amphibole (very few have pyroxene). It is vesicular.
What is vesicular andesite?
Rocks formed from water that contains dissolved materials
What is a chemical sedimentary rock?
Metamorphic changes in rocks that occur in localized areas. Can form Hornfels.
What is contact metamorphism?
The 8 properties that geologists use to identify minerals.
What are Luster, Streak, Atomic Arrangement, Cleavage, Fracture, Hardness, Crystalline Structure, and Color?
