Rock Cycle
A model that describes the formation, the breakdown and the reformation of rock.
What is the Rock Cycle?
Creates lose material called sediments.
What is weathering?
Type that has large crystals and many colors.
What is slow cooling - Intrusive Igneous Rock?
At depths of 16km, the pressure can be ______ times greater than the pressure of the atmosphere at the surface.
What is 4000?
Separate from water that passes through the sediment to form a natural cement that binds the rock and mineral fragments into sedimentary rock
What are dissolved minerals?
The two processes that are involved in making metamorphic rock.
What are heat and pressure?
Sediments are deeply buried, placing them under pressure because of the weight of overlying layers.
What is compaction?
The dark-colored rocks are rich in calcium, iron, and magnesium and poor in silicon
What is mafic?
The greatest change takes place where magma comes into direct contact with the surrounding rock
What is contact metamorphism?
The process in which sedimentary rocks are arranged in layers.
What is stratification?
The two processes involved in making igneous rock.
What is heating and cooling?
Caused by increase in temperature in rock deep below the surface of Earth
What is melting?
A large amount of lava covers a large amount of land, sometimes pre-existing landmarks may be covered.
What is a lava plateau?
________ in rock are structures that indicated that a rock has been deformed
What are folds?
Forms underground when partially decomposed plant material is buried beneath sediment and is changed by increasing heat and pressure
What is coal?
Found near volcnaoes and fissures.
What is Igneous Rock?
The process by which sediment is removed from its source
What is erosion?
The light-colored rocks are rich in elements such as aluminum, potassium, silicon and sodium.
What are felsic rocks?
The texture of metamorphic rock where the mineral grains are not arranged in planes or bands
What is non-foliated?
Forms from solutions of dissolved minerals and water
A naturally occurring solid mixture of one or more minerals and organic matter
What is a rock?
Process in which sediment moved by erosion is dropped and comes to rest
What is deposition?
Forms from lava that erupts, or extrudes onto the Earth’s surface
What is extrusive igneous rock?
The texture of metamorphic rock in which the mineral grains are arranged in planes or bands
What is foliated?
Made of fragments of rocks cemented together by a mineral such as calcite or quartz.
What is clastic sedimentary rock?
