Sedimentary Formation
Small pieces of rock that are moved and deposited in a variety of ways.
What are sediments?
What are fossils?
The most common type of sedimentary rock.
What is clastic?
What are metamorphic rocks?
True or False: Any type of rock can become another type of rock.
True
The process of removing and transporting sediments
What is erosion?
The horizontal layering of sedimentary rocks.
What is bedding?
This type of sedimentary rock is formed from the remains of organisms.
What is biochemical?
Metamorphic rocks that have layers and bands of minerals.
What is foliated?
The type of rock that forms when magma cools and minerals crystallize.
What is igneous?
The agent of erosion that can only move small grains.
What is wind?
A type of bedding in which particles near the bottom layers are heavier and coarser. This type of bedding is common underwater.
What is graded bedding?
[DAILY DOUBLE] Often found in medium-grained sedimentary rocks, this is the percentage of open spaces between the grains in a rock.
What is porosity?
Metamorphism that occurs when molten material comes into contact with solid rock.
What is contact metamorphism.
The type of rock that forms when sediments experience deposition, burial, and lithification.
What are sedimentary?
The stage of lithification in which minerals grow being the grains of sediments, essentially "gluing" the sediments into a sedimentary rock.
What is cementation?
What are ripple marks? [can accept ripples]
This type of sedimentary rock is formed as grains are left behind in a body of water via precipitation and evaporation.
What is chemical?
[DAILY DOUBLE] Metamorphism that occurs over a large region of Earth's crust.
What is regional metamorphism?
The type of rock that forms when any type of rock is exposed to high amounts of heat and pressure.
What is metamorphic?
The stage of lithification in which sediments are forced closely together, almost as if they are being squeezed.
What is compaction?
Sediment grains with harder minerals can travel much further before breaking. Therefore, they experience more of this process that wears down the edges of sediment grains.
What is rounding? [can also accept sorting]
This type of clastic sedimentary rock that forms barriers due to the small size of its particles, typically between 1/16 mm and 1/256 mm.
What is fine-grained?
Metamorphism that occurs when rock comes into contact with hot water.
What is hydrothermal metamorphism?
Describe how an igneous rock could become another igneous rock. (Hint: At least 2 things need to happen)
