The Rock Cycle
100
Igneous rock forms from this.
What is magma?
100
These are the 2 broad classifications for Igneous rocks?
Intrusive and Extrusive
100
Pieces of solid material that have been deposited on Earth's surface by wind, water, ice, gravity or chemical precipitation.
What is sediments?
100
These are the two types of Metamorphic rocks we discussed?
Foliated and non-foliated
100
These two things are needed to turn Igneous or sedimentary rocks into Metamorphic rocks.
What are extreme heat and pressure.
200
Fine grained igneous rocks that cool quickly on Earth's surface.
What are extrusive igneous rocks?
200
This term is used to describe the texture of a rock with large crystals.
What are coarse grained?
200
The process of in which sediments are laid down on the ground or sink to the bottom of bodies of water.
What is deposition?
200
Metamorphic rocks are created due to these two things.
What are extreme heat and pressure.
200
Magma, through cooling and crystallization turns into this type of rock.
What is Igneous rocks?
300
Magma that flows out onto Earth's surface.
What is lava?
300
This glassy rock cools very quickly from lava.
What is obsidian.
300
Physical and/or chemical processes that transform sediments into Sedimentary rocks.
What is cementation?
300
Wavy layers of light and dark minerals within metamorphic rocks.
What is Foliation?
300
This must happen for Metamorphic rocks to become Igneous rocks.
What is melting, cooling and crystallization?
400
Course grained igneous rocks that cool slowly beneath the Earth's surface.
What are Intrusive Igneous Rocks?
400
This rock has vesicles, or holes, left behind as gasses escaped rapidly as lava cooled.
What is pumice?
400
This sedimentary rock has cobble and pebble sized rocks that were deposited as sediment and cemented together.
What is a conglomerate (breccia)?
400
Metamorphic rocks with fine grained, uniform, random crystals are classified as this.
What is non-foliated?
400
This must happen for Igneous rocks to become Sedimentary rocks.
What are uplift, weathering and erosion?
500
Lighter colored igneous rocks contain this mineral.
What is quartz?
500
This intrusive igneous rock is similar to granite, but has EXTRA large crystals due to extremely slow cooling.
What is pegmatite?
500
Coal is an example of this type of sedimentary rock.
What is biochemical?
500
The Great Smoky Mountains are an example of this type of metamorphism.
What is the regional metamorphism?
500
This must happen to allow weathering and erosion to take place.
What is uplift.
