Metamorphism
Non foliation
Foliation
Recrystallization
100
The process in which an existing rock is changed by heat or pressure - or both
What is metamorphism
100
This occurs over small areas.
What is metamorphic changes.
100
The mineral crystals in this rock are not lined up.
What is non foliation rocks
100
An arrangement of minerals in flat or wavy parallel bands.
What is foliation
100
A sedimentary rock that forms near the surface. It can be buried deeper as blocks of the crust push together.
What is shale
200
Heat and pressure can break the bonds that join atoms in minerals and then the atoms can join together differently as new bonds form.
What is Recrystallization
200
This depends on the types of parent rocks and the conditions of temperature and pressure.
What is the types of metamorphic changes.
200
It forms from sandstone that is made up of almost entirely out of pieces of quartz.
What is quartzite
200
This consists almost entirely of one type of mineral that does not show foliation
What is a metamorphic rock
200
As pressure causes the minerals to line up the layers. Mica starts to grow as recrystallization begins.
What is slate
300
An arrangement of minerals in flat or wavy parallel bands.
What is foliation
300
Small areas of rock can be also be formed by high pressure alone.
What is metamorphic rock
300
One common non foliation metamorphic rock develops from limestone.
What is marble
300
Higher levels that the rocks tend to separate into light and dark bands, like those in gneiss.
What is metamorphism.
300
This goes deeper in the crust, where the temperature and pressure are higher.
What is phyllite
400
The original Sedimentary or igneous rock.
What is Parent rock
400
This is hot enough to bake the surrounding rocks into metamorphic rocks.
What is magma
400
This is used as a decorative stone. It is good for carving and sculpting.
What is marble
400
This is a foliated metamorphic rock that contains several types of minerals.
What is phyllite
400
As recrystallization increases, completely new types of minerals replace older ones.
What is schist
500
Develops when rocks are under pressure.
What is foliation rocks
500
This can push into rock layers and cause changes over areas ranging from a few centimeters to tens of meters.
What is magma
500
When magma or lava touches other rocks.
What is non foliation
500
This can grow and make the mineral/rock look shinny.
What is mica
500
During recrystallization, light and dark minerals separate into bands. Changes are so great that all traces of the original shale are gone.
What is gneiss
