Common metamorphic rocks
Foliation
Nonfolitated Rocks
100
an arrangement of minerals in a flat or wavy parallel bands
What is foliation?
100
Molten rock that cools near or at Earths surface hardens quickly
What is Basalt?
100
A sedimentary rock that forms from the surface.
What is shale?
100
Can be split into thin sheets along the boundaries between its flat bands of minerals
What is Slate?
100
Rocks that don't show foliation
What is Nonfolitated Rocks?
200
the process in which an existing rock is changed by heat and/or pressure
What is metamorphism?
200
Rhyolite, pumice, and basalt are in this type of igneous rock
What is Extrusive?
200
Pressure causes the minerals to line up in layers
What is slate?
200
Bands are extremely thin
What is Low levels of Metamorphism?
200
A Nonfoliated rock that is a decorative stone
What is Marble?
300
Metamorphic rocks that contain several minerals develop foliation under pressure
What is Folitation in Metamorphic Rocks?
300
This rock is made from molten rock or lava
What is igneous rock?
300
Found deeper in the crust, where the temperature and pressure is higher
What is phyllite?
300
A mineral named mica can grow and make the rock look shiny
What is High levels of Metamorphism?
300
Forms from sandstone which is mostly made up of pieces of its kind
What is Quartzite?
400
the process in which a mineral's atomic bonds are broken and rejoined in new ways
What is recrystallization?
400
This rock is made from loose material from older rock which are then cemented together to form
What is sedimentary rock?
400
As recrystallization increases, new types of minerals replace older ones
What is Schist?
400
Temperature and pressure continue to increase which mineral's seperate
What is Light and Dark bands?
400
A metamorphic rock that has not been subjected to high pressure
What is Hornfels?
500
Changes can occur over hundreds of kilometers or just a few centimeters
What is Metamorphic Changes?
500
A set of natural processes that form, change, break down, and, re-form rocks
What is a Rock Cycle?
500
During recrystallization, light and dark minerals seperate into bands
What is Gneiss?
500
Rocks produced by metamorphic changes that affect large areas
What is Common Foliation?
500
made up mainly of one type of mineral
What is a Metamorphic rock that doesn't display foliation?
